The track was noted for its emotionally vacant choir effect, and the recurring onomatopoeia "beep beep" that Bowie had first used in an unreleased 1970 song called "Rupert the Riley".[1] Another phrase in the lyrics that Bowie borrowed from his past was "People from Bad Homes", the title track of a 1973 album he recorded with his protégés The Astronettes, which went unreleased until 1995.[6]
