"Holiday in Cambodia" is a song by American punk band the Dead Kennedys. The record was released as the group's second single in May 1980 on Alternative Tentacles with "Police Truck" as its b-side. The title track was re-recorded for the band's first album, Fresh Fruit for Rotting Vegetables (1980); the original recording of the song, as well as the single's b-side, are available on the rarities album Give Me Convenience or Give Me Death (1987). The photograph in the front cover of the single was taken from the Thammasat University massacre in Thailand, and depicts a member of the right-wing crowd beating the corpse of a student protester with a metal chair.
The song is an attack on an stereotypical, moralizing, privileged American college student. Its lyrics offer a satirical view of young, well-to-do and self-righteous Americans, contrasting such a lifestyle with the brutal dictatorship of the Khmer Rouge, led by Pol Pot (depicted on the original single's label and mentioned in the lyrics), who killed more than a million people in Cambodia between 1975 and 1979.
The re-recording of this song that appears on Fresh Fruit for Rotting Vegetables is different from the single version, being fifty-five seconds longer, at a higher tempo and featuring an extended, surf-influenced intro, as well as an extended bridge. While the original lyrics include the satirically quoted word "niggers", subsequent performances by the reformed Dead Kennedys and various other artists who have recorded the song over the years have omitted it substituting other words in its place. When the song was featured in Rock Band 2 as a downloadable track, along with two other songs by the group, the word was replaced with "brothers", and in performances over the years with other groups, Jello Biafra has often used "blacks". The song also mentions the controversialDr. Seuss short story "The Sneetches".
In October 1998, Biafra was sued by former members of Dead Kennedys. According to Biafra, the suit was a result of his refusal to allow "Holiday in Cambodia" to be used in a commercial for Levi's Dockers; Biafra opposes Levi's due to what he believes are their unfair business practices and sweatshoplabor. However, the other members claimed that their royalties had been defrauded. "The record industry has been skimming royalties owed artists since the beginning," according to Dead Kennedys' guitarist East Bay Ray. "This case is no different from blues musicians being taken advantage of in the twenties and thirties. Many people doubted the claims we made against our former record label back in 1998 but with this announcement there is no denying we were the victims here."
