Years later, Kubrick refused Roger Waters permission to use audio samples from his film 2001: A Space Odyssey on Waters' solo album Amused to Death. It can be seen on a shelf in the music shop scene. Kubrick did, however, include the album cover in the film. Stanley Kubrick wanted to use this track for his film A Clockwork Orange however, the band refused permission. The song was the last Pink Floyd composition which was credited as being co-written by someone outside the band prior to 1979 (not counting Clare Torry's contribution to ' The Great Gig in the Sky', for which she has been retroactively given credit due to a settlement with Pink Floyd). When Roger Waters heard David Gilmour playing the guitar parts for this track, he said that he thought it sounded like the theme song from the western film The Magnificent Seven. Roger Waters and Nick Mason had to play for twenty-three minutes straight.

Recording began with the drum and bass parts, recorded in one take for the entire suite, resulting in an inconsistent tempo throughout the song.
