The album contains cover versions of three songs: "Cactus" by Pixies, which features Bowie on all instruments except for bass and is his only recorded drum performance, "I've Been Waiting for You" by Neil Young (which had also been recorded by Pixies as a B-side for 1990's "Velouria" single), and "I Took a Trip on a Gemini Spaceship" by Norman Odam, aka the Legendary Stardust Cowboy, from whom Bowie lifted part of his "Ziggy Stardust" moniker in 1972. The latter two songs were taken from a list of songs that Bowie compiled in the 1970s for his never-recorded "Pin Ups 2" album.
