Halloween Playlist: 10 Songs Inspired by Classic Horror Movies

Halloween is my favorite holiday, partly because it's a great excuse to watch classic horror movies, and partly because I get to trot out my Halloween playlists of songs about vampires, werewolves, and other things that go bump in the night. (OK, so I listen to them all year round, but this time of year they just sound cooler.) Actually, a lot of great pop and rock songs have been directly inspired by classic horror films, and not just the most popular movies that everyone already knows. If you're looking for something to listen to this week while you fill your streaming queues with Hammer horror, Universal monsters, and other ghoulish goodies, here are ten of my go-to favorites for a classic horror Halloween playlist.

1) "Nosferatu" by Blue Oyster Cult - The 1922 silent vampire classic from F.W. Murnau is the direct inspiration for this song from the band best remembered for "Don't Fear the Reaper." The song actually covers the plot of the whole movie, and it's creepy enough to deserve a top spot on any Halloween playlist.

2) "Ballad of Dwight Fry" by Alice Cooper - Horror icon Dwight Frye played Renfield in the 1931 Dracula and also appears in supporting roles in other Universal horror classics, so it's no shock that Goth god Alice Cooper might want to sing Frye's praises. In the song, Cooper impersonates the kind of character Frye often played, not the actor himself.

3) "The Creature from the Black Lagoon" by Dave Edmunds - The Universal monster gets his own theme song with a rock n roll groove; the song appeared on the 1979 album, Repeat When Necessary. The Creature doesn't get as much love as some of the earlier monsters, so I appreciate this song for giving our watery friend some overdue musical attention.

4) "I Walked with a Zombie" by Roky Erickson - Released in 1981, Roky Erickson's album, The Evil One, is full of Halloween treats for monster fans, including this tribute to the 1943 film from producer Val Lewton and director Jacques Tourneur. Check out the rest of the album for "Night of the Vampire" and "Creature with the Atom Brain." A new version of The Evil One was released in September 2013.

5) "Blood and Roses" by The Smithereens - J. Sheridan Le Fanu's sapphic vampire Carmilla got a sexy update with the 1960 film of the same name, which then inspired this moody lament from The Smithereens. The song captures the vampire's sense of longing and exclusion from the world of the living beautifully, although most people who hear it probably don't recognize its cinematic roots.

6) "Werewolves of London" by Warren Zevon - This rocking werewolf anthem specifically calls out Lon Chaney Sr. and Jr. as its horror icons, but the title also recalls the 1936 film, Werewolf of London, which stars Henry Hull, Warner Oland, and Valerie Hobson.

7) "Bela Lugosi's Dead" by Bauhaus - You really can't have a classic horror playlist without this song inspired
by the great Lugosi, who became immortal as Count Dracula but played many other memorable horror roles.

8) "Batman, Wolfman, Frankenstein or Dracula" by The Diamonds - Any classic horror fan can appreciate this song's theme and wicked sense of humor. The speaker in the song takes his date to horror movies because that's the only thing that turns her on: "She gets romantic, it's really quaint/ When all the other women start to faint."

9) "Monster Mash" by Bobby "Boris" Pickett - Here's another one you just can't have a Halloween playlist without. All of the classic movie monsters do the mash in this much-played rock novelty tune.

10) "Howl" by Florence + The Machine - This memorably Gothic track from the band's 2009 album, Lungs, uses the ominous motto from The Wolf Man (1941) as its refrain. "Even a man who is pure of heart, and says his prayers by night, may become a wolf when the moon is full..."

Halloween Music for Classic Horror Fans



Plenty of songs have been inspired by classic horror films. In fact, you can easily make a whole playlist of them to get you in the mood for the upcoming chills and thrills of the spectral season. Here are a few of my favorite songs that trace their origins back to classic horror movies.

"The Monster Mash" by Bobby "Boris" Pickett - Of course, it's the obvious choice for Halloween, with references to all of the old Universal monsters and creatures. Like Michael Jackson’s “Thriller,” you just can’t have a Halloween playlist without it.

"Bela Lugosi's Dead" by Bauhaus - Almost 10 minutes long, this Goth classic pays homage to horror star Bela Lugosi, best known as the iconic vampire in Dracula (1931).

"Pinhead" by The Ramones - Inspired by Tod Browning's Freaks (1932), this punk rock classic quotes some of the film's most famous lines, "We accept you...One of us." Also check out their song, "Pet Sematary," which is one of my personal favorites for this time of year. It’s spooky and mournful with just enough rocker edge.

"Batman, Wolfman, Frankenstein or Dracula" by The Diamonds - Like "The Monster Mash," this song from the 1950s refers to lots of well known monsters and creatures, but its humorous twist is more disturbing because the speaker in the song finds out that his girlfriend only feels romantic when they're watching horror movies!

"Boris Karloff" by The Barbarellatones - If Bauhaus can pay tribute to Bela, then Boris also needs some love. The band gets added points for having a name inspired by the cult classic, Barbarella (1968), starring Jane Fonda. Karloff made many great classic horror movies, among them Frankenstein (1931) and The Mummy (1932).

"I Was a Teenage Werewolf" by The Cramps - These punk rockers really loved old horror movies, including the 1957 film of the same name starring a very young Michael Landon. Plenty of later songs take their cue from either this film or The Cramps song about it, including several about Remus Lupin from the Harry Potter novels.

"Werewolves of London" by Warren Zevon - This popular song was inspired by The Werewolf of London (1935), which set the tone for many werewolf movies to come.

"I Walked with a Zombie" by Roky Erickson and The Aliens - Horror maestro Val Lewton is best remembered today for the original Cat People (1942), but Roky Erickson and The Aliens give up some love for Lewton's take on Jane Eyre - with zombies! - in this song that shares the name of the 1943 film.

"Eyes Without a Face" by Billy Idol - 80s punk star Idol makes direct reference to the 1960 horror masterpiece by director Georges Franju; the backup singers during the chorus are actually saying the name of the film in its original French, Les Yeux Sans Visage.

"Nosferatu" by Blue Oyster Cult - Nobody can be surprised that the band best known for "Don't Fear the Reaper" liked classic horror films. Here, they take their inspiration from the 1922 silent film from F.W. Murnau. The song actually retells the story of the movie.

"Return of the Fly" by The Misfits - The Misfits loved classic horror a lot, and they recorded quite a few songs inspired by their favorite movies, including this one, which refers to the 1959 Vincent Price film. Try "Die, Die My Darling," inspired by Tallulah Bankhead's last film, or "Abominable Dr. Phibes," also a Vincent Price picture, for more of their horror tributes.

"The Creature from the Black Lagoon" by Dave Edmunds - Old school rocker Edmunds sings this tribute to the aquatic member of the classic monster gang; the title comes from the 1954 film.

"Peter Lorre" by Satan's Pilgrims - Don't let the band's name fool you. This is a surf rock tribute to the classic horror star and great character actor. The very idea of a surf rock song being named after Peter Lorre is wonderful. Catch Lorre himself in M (1931), Mad Love (1935), and Arsenic and Old Lace (1944), as well as in The Maltese Falcon (1941) and Casablanca (1942).

"Ballad of Dwight Fry" by Alice Cooper - Even though Cooper leaves the last letter off of Dwight Frye's name, this song still merits attention for its celebration of the great horror actor, most remembered for his portrayal of Renfield in the 1931 version of Dracula. Frye also appeared in Frankenstein (1931) and The Vampire Bat (1933). Cooper's song adopts the perspective of a Renfield sort of character, and it’s a must-have for fans of either the actor or the Goth rock star.

Need more? Try Florence + The Machine’s “Howl,” which quotes The Wolf Man (1941), Ookla the Mok’s “Bride of Wolfman,” and vampire-inspired hits like Sting’s “Moon Over Bourbon Street” and Concrete Blonde’s “Bloodletting.” Also, let me know in the comments section about your favorite songs inspired by classic horror films!

Gothic Angels: The Dead, Good Girl in Robert Browning’s “Porphyria’s Lover” and Alice Cooper’s “Cold Ethyl”


With so many representations of the femme fatale in art, music and literature, a man might consider himself duly warned against the seductive charms of the destructive woman, but being forewarned is no assurance that a man will entirely escape the shame and suffering of betrayal from the one he loves. How does a man make sure that his girl will stay true? Sometimes the sweetest face can disguise a devil’s lying tongue, and the girl who seems loyal might actually be treacherous when the man is not around. In “Porphyria’s Lover” and “Cold Ethyl,” Robert Browning and Alice Cooper offer one solution to this problem that, although grotesque, is remarkably effective. Both the poem and the song feature men who can rest assured that their lovers will always be good girls because they are dead. While macabre in their approach to the problem of women’s fidelity, Browning’s poem and Cooper’s song demonstrate the lengths to which men are willing to go in order to avoid betrayal by a potential femme fatale and ensure the permanent loyalty and “love” of a gothic version of the domestic angel.

In “Porphyria’s Lover,” the lover of the title is frustrated by his relationship because of his inability to control the girl he loves. Porphyria is unwilling to commit, and she prefers to remain beyond the lover’s control and inside her own world of wealth and society. While not exactly a femme fatale on the same level as Keats’ belle dame sans merci, the lover sees Porphyria as a woman who is veering dangerously close to being more whore than virgin because her materialism and vanity take precedence over her emotional attachment to him. The lover summarizes this problem with Porphyria very succinctly; he describes her as
Too weak, for all her heart's endeavour, 
To set its struggling passion free    
From pride, and vainer ties dissever,    
And give herself to me for ever. (22-25)
Angels should care more for love than money, but Porphyria either cannot or will not fit the mold into which her lover wishes to cast her. The lover’s solution to this problem is to render Porphyria completely passive by strangling her with her own hair. Now she can no longer resist the angel role or the lover’s complete control over her; she will remain “perfectly pure and good” forever (37). The fact that she is dead does not cloud the lover’s joy at her newfound perfection; he insists that she is happier this way and that their macabre union has the de facto blessing of God since He “has not said a word” in condemnation of the lover’s actions (60). The lover ends the poem locked in a morbid embrace with his perfect, blonde, angel corpse; the reader, who can imagine the inevitable decay of Porphyria’s remains, recoils in horror, but the lover is satisfied because his conflict was with Porphyria’s will, and that troublesome part of her has been utterly erased by her death.

In the song, “Cold Ethyl,” Alice Cooper provides a logical continuation of Browning’s theme by depicting a man whose perfect girlfriend is also a corpse, although Cooper’s song takes the macabre situation to the next level by highlighting the sexual nature of the speaker’s relationship with the dead body. The speaker blatantly talks about having sex with the deceased woman:
One thing,
No lie,
Ethyl's frigid as an Eskimo pie.
She's cool in bed,
Well, she oughta be 'cuz Ethyl's dead! (Cooper)
The humorous undercurrent that characterizes Cooper’s most lurid songs is obvious in the pun about Ethyl being “frigid,” a term that describes both anything refrigerated or cold and a woman with no sexual passion. The speaker never tells us where he got this corpse, and we do not know if he, like Porphyria’s lover, is a murderer as well as a necrophiliac, but Cooper’s speaker is far more practical about his dead angel because he preserves her by keeping her in a refrigerator. Porphyria’s delusional lover never thinks much about the natural decay of corpses, but Cooper’s speaker clearly understands that his permanently perfect lover will only stay desirable if he keeps her on ice. Like Porphyria’s lover, however, Ethyl’s necrophiliac boyfriend sees a corpse woman as the perfect mate because she is completely passive and permanently available to him. The speaker brags that “everything is my way / Ethyl don’t have much to say.” Like Porphyria’s lover, he has total control in the relationship. The speaker ends the song with the following declaration:
If I live 'til ninety-seven
You'll still be waiting in refrigerator heaven
'cuz you're cool,
You're on ice,
Cold Ethyl,
You're my paradise.
The dead Ethyl makes an ideal lover because she is never going to leave the speaker or betray him by having wishes contrary to his own; her passivity and reliability make her the speaker’s “paradise,” a perfect angel woman who will never break the speaker’s heart. Like Porphyria’s lover, Cooper’s speaker has taken the idea of the angel woman to an extreme that seems horrific, if also grimly comical, to the audience, but he himself seems very well satisfied with the situation.

Both “Porphyria’s Lover” and “Cold Ethyl” rely upon a certain amount of shock value in their appeals to their audiences; necrophilia is a topic bound to give people the willies, either pleasurable or otherwise. Still, both the poem and the song explore the territory of the virgin/whore dichotomy in an interesting way because they show the extreme end of masculine desire to avoid the dominating power of the femme fatale and ensure the sexual and emotional fidelity of the adored angel. The men in both texts want so much control and power over the women in their lives that they find only corpses are passive enough to be satisfactory. Ironically, their frozen gothic angels are the only women who can live up to the expectations of these grotesque and greedy lovers.

Sing a Song of Superman


Kingdom Come (DC/Aspect)
     Since Superman has appeared in practically every possible medium from radio programs to pajama sets, it should be no surprise that he also has a strong presence in song, although the extent of that presence is probably underestimated by most, even by those who consider themselves real fans as opposed to casual admirers. Superman’s presence in popular music goes far beyond the mere use of his name, although such use is itself extremely common. In fact, an impressive number of songs have been written specifically about the Man of Steel; these songs might take the form of provocative commentaries and dramatic monologues envisioning the perspectives of Superman, Clark Kent, Lois Lane and even Jimmy Olsen, or they might create extended metaphors about modern life that hinge on the Superman characters. Taken together, Superman songs create a thought-provoking vision of this beloved American icon; they emphasize qualities that we don’t generally associate with the character in the broader cultural context formed by all of his other various guises. Rather than strength and confidence, these songs voice anxiety and doubt, longing and loss as the basic elements of Superman’s character. This aspect of the character certainly exists in other media and has even been explored in several important comic texts, beginning perhaps with Jerry Siegel’s story, “Superman’s Return to Krypton,” back in 1960 and culminating with Mark Waid and Alex Ross’ 1996 mini-series Kingdom Come. This vision of Superman as an icon of suffering and anxiety has steadily gained ground in comics, films and television over the last decade or so, but nowhere is it more prevalent than in the melancholy voices that come out of musical interpretations of the Superman story.

            It is important to note that these are songs that are meant for adults. The bands that record these songs are not children’s entertainers, novelty groups or teen pop idols. Neither are the songs primarily intended for an audience of comic book readers or self-declared fans. The songs tend to fall into the “alternative” and “rock” categories, where the average listener is college age or older. This perceived audience for Superman songs makes the pervasive anxiety and suffering of the songs make a great deal more sense. In “Superman and the Dreams of Childhood,” Jane W. Kessler argues that children admire Superman because of his strength; children want a Superman whose invulnerability and courage comfort them. In Super Heroes: A Modern Mythology, Richard Reynolds writes that Superman embodies the desires of adolescence through his physical mastery of the world around him (66). For adults, the key elements of Superman’s character are his anxiety about failure, his sense of loss, and his response to the pressure of being constantly expected to live up to the needs and demands of those who depend on him. These are the very elements that the songs emphasize; they are also, of course, the elements that comic, television and film versions of the Superman story have increasingly begun to explore as the perceived audience for such productions changes from child and teen to adult.

            Songs about Superman are nothing new; they date at least as far back as 1966, when Donovan first released the often-covered single, “Sunshine Superman.” In 1969 The Clique recorded the song, “Superman,” for their self-titled album; it was later re-popularized when R.E.M. covered it in 1986 for the album, Lifes Rich Pageant. 1977 saw the release of Barbra Streisand’s album, Streisand Superman, which featured the song, “Superman.” In 1979, The Kinks album, Low Budget, included the song, “(Wish I Could Fly Like) Superman.” These earlier examples of Superman songs tend to focus on the character’s powers or present fairly simple visions of what it means to be Superman. Characters who obviously aren’t Superman generally long for his abilities or metaphorically claim his identity to represent their own feelings of invulnerability or power. Many of the early songs do little more than evoke the name of Superman in passing, as is the case with “Sunshine Superman.” The Clique song, perhaps, hints best at the mood that comes to dominate Superman songs, since its lyrics betray a certain irony; “I am Superman,” the speaker declares, “And I can do anything,” but his tone as he sings is both desperate and bitter, and the other lyrics imply that he is unable to get the attention of the girl he desires, even though he claims that she does not love the man she is with. Even The Clique song lacks the kind of extensive metaphor and character development that become more prominent in later compositions, but the early works do demonstrate the extent of Superman’s appeal as a subject for songs and the long history of his appearances there.

George Reeves as Superman (Wikimedia Commons)
Over the last two decades, the number of popular songs that focus on Superman has increased dramatically, and these works suggest a trend toward more sophisticated and problematic visions of the Man of Steel. Not surprisingly, perhaps, Don McLean would be the first songwriter to take the idea of Superman in a darker direction. Famous for his complex and even mythical song, “American Pie,” McLean is known for his engagement of tragic icons and difficult cultural moments, from the deaths of the Big Bopper, Richie Valens and Buddy Holly to the artistic suffering of Vincent Van Gogh. McLean’s “Superman’s Ghost,” which was first released in the UK in 1989 on the album And I Love You So, merges the fictional Superman character with the real actor, George Reeves, who played Superman on the 1950s television program and died under mysterious circumstances in 1959. In the song, the speaker tells us, “I flew to the coast, where Superman’s ghost/ Lay shot on the bedroom floor./ He said, ‘Watch out for TV, it crucified me,/ But it can’t crucify me no more.” The speaker himself identifies with the merged Superman/Reeves figure, lamenting his “terminal Metropolis blues” and repeatedly depicting the pressure placed on any public person, whether superhero, actor or singer. In the chorus of the song, the speaker says, “I don’t wanna be like old George Reeves,/ Stuck in a Superman role./ I’ve got a long way to go in my career,/ And some day my fame it will make it clear/ That I had to be a Superman.” For McLean, being a Superman is more obligation than honor, more perilous than pleasurable, as the fate of George Reeves makes clear. It’s an idea that continues to take shape as later artists return to the Superman figure in their own songs.

Spin Doctors album cover (Sony)
While McLean’s work presents something of a forerunner to the trend, 1991 marked the beginning of a more definitive upswing in songs about Superman; that year produced two notable examples, both of them very successful and widely played on radio stations around the country. The Spin Doctors released “Jimmy Olsen’s Blues” on their album, Pocket Full of Kryptonite, and the Crash Test Dummies recorded “Superman’s Song” for their first album, The Ghosts That Haunt Me. Neither of these songs depicts much happiness in Metropolis. The Spin Doctors paint Jimmy Olsen as a jealous but unrecognized rival for Lois Lane’s affections, while the Crash Test Dummies mournfully sing of Superman’s difficult struggle to fight for justice in contrast to Tarzan’s simple jungle life. The Spin Doctors song is essentially comic; Jimmy’s phallic confidence in his “pocket full of kryptonite” as a match for Superman’s charms is undoubtedly amusing, although his refusal to admire Superman as a hero or admit his superior merit works against the traditional image of the Jimmy Olsen character as devoted acolyte. While the tone of “Jimmy Olsen’s Blues” is more upbeat, “Superman’s Song” is performed as a dirge, with the speaker lamenting in the refrain, “And sometimes I despair the world will never see another man like him.” The speaker focuses on Superman’s selflessness and his loss of Krypton; he conjectures that Superman must have been tempted to leave behind his thankless work and join Tarzan in the jungle. The tone of the song and the speaker’s consistent use of the past tense imply that Superman is no more, although, ironically, the comic book death of Superman at the hands of Doomsday would not occur until 1993. Of the two, “Superman’s Song” is the more provocative piece, and its downbeat approach to the Man of Steel has proven to be more popular in the songs that have appeared afterward.

             In 1997, Big Head Todd and The Monsters contributed to this trend with  “Resignation Superman,” on their album, Beautiful World. As the title suggests, the song presents a Superman who leaves behind his struggle to fight against crime; in the refrain, the speaker imagines Superman saying, “Yes, I turn my back on this world,/ Yes, I turn my eyes from this world.” The speaker goes on to imagine Superman longing to settle down, raise a family, and enjoy a life of his own. In the speaker’s vision, Superman stays at home and watches the evening news but does nothing to intervene, only observing that he “broke [his] back on this world” and is now done with it. The words of the song’s chorus imply that Superman’s desertion signifies God’s absence, as well; “Oh, Lord,” the speaker prays, “I need to believe in you now that I’m suffering/ Oh, Lord, I need to receive your hand in my heart.” The rest of the song, however, presents a world in which neither Superman nor God will play any further part, both of them, presumably, fed up with human behavior and no longer interested in saving people from themselves. The musical component of the song features a heavy percussive beat more typical of rock, which makes it seem less mournful than the slow-paced “Superman’s Song,” but the lyrics themselves are even more depressing, since The Crash Test Dummies only speculate that Superman must have thought about quitting, while Big Head Todd tells us that he actually has.

The advent of the twenty-first century has brought with it an impressive expansion of the Superman song canon, and almost all of the bands singing about Superman follow the leads of Don McLean, The Crash Test Dummies and Big Head Todd to offer similarly conflicted and angst-ridden perspectives. Among the songs to appear since 2000, to name only a few, are “When I Was Superman” by The Uninvited, “Superman (It’s Not Easy)” by Five for Fighting, “New Superman” by The Hillcats,  “Lois Lane” by Holly Long, “Superman” by the JordanSax Band, “Superman” by Stereophonics, “Man of Steel” by Donnie Singer, and “Superman is Sleeping In” by Ritt Henn. Of the lot, The Hillcats song, “New Superman,” is probably the most optimistic, since it tells the story of an average guy who inherits the mantle of the Man of Steel when he finds the abandoned costume in a phone booth, but even here the idea that the old Superman would quit suggests that the job is not as great as we might like to imagine.

Five for Fighting’s “Superman (It’s Not Easy)” has become one of the best-known of the recent songs, thanks in equal parts to its popularity following the September 11 attacks and its use on the Smallville soundtrack, where it functions as the de facto theme of the program for fans, who prefer it to the official theme, Remy Zero’s “Save Me.” Singer-songwriter John Ondrasik, the sole member of Five for Fighting, first released the song on the 2000 album, America Town. As the title suggests, the song emphasizes the difficulties of being Superman, whose anxiety and weariness are so pervasive that he takes no joy in his ability to fly. Ondrasik’s song functions as a dramatic monologue, giving us an inside perspective on Superman’s suffering and depression; the mournful vocals and piano accompaniment complement the emotional tone of the lyrics, creating an especially moving vision of what it means to be a man on whom the fate of the world very literally depends. Superman himself seems broken, discouraged and troubled by the world’s insistence on his strength in spite of his own feelings of loss and anxiety; in the second verse, he says, “Wish that I could cry,/ Fall upon my knees,/ Find a way to lie/ About a home I’ll never see.” The lyrics share many elements in common with the Crash Test Dummies song, including grief over the loss of Krypton and a persistent sense of Superman’s role as a sacrifice of himself for the good of others. To many listeners, the Five for Fighting song must seem like a very original and even revelatory perspective on Superman, but it is, in fact, merely a more recent and more popular working out of a familiar theme for Superman songs. 

A perfect, confident Superman does not speak to a postmodern, adult sensibility of the world in which we live; we want to see him face the problems that define our own struggles and experiences, and that is the vision of Superman that these songs repeatedly offer. The Golden Age Superman, with his moral certainty and unwavering spirit, might comfort children and inspire adolescent boys with a longing for power, but he offers little to adults. The Superman imagined by Don McLean, the Crash Test Dummies, Big Head Todd and Five for Fighting is a character with whom adults can identify and whom they can admire because he shares their problems and struggles to overcome them. Sometimes he feels like quitting; sometimes he does quit. Adults know this feeling of hopelessness and frustration and understand why a hero might suffer from it. These songs also attempt to address the presence or absence of Superman in the world as a metaphor for the crisis of faith that is an important aspect of postmodernism, particularly in a post 9-11 America. Children believe in Superman as they believe in God, unconditionally, but adults experience doubt, and songs like those by the Crash Test Dummies and Big Head Todd address that uncertainty.

More than anything else, a look at Superman songs demonstrates the adaptability of the Superman icon and shows how Superman can be different things to different audiences; alternate versions of the character exist in different media depending on the identity and desires of the target audience. It is also a testament to the power of this iconic figure that musicians have been singing songs of Superman for more than forty years, with no diminution of his appeal in sight. Our songs about Superman reflect our own anxieties about life, faith and responsibility, but they also reflect how much we need Superman, if not to rescue us from our problems, then at least to show us that we do not bear these burdens alone.
