- Bassist Roger Waters wrote “Part 2” as a protest against rigid schooling, particularly boarding schools. “Another Brick in the Wall” appears in the film based on the album. In the “Part 2” sequence, children enter a school and march in unison through a meat grinder, becoming “putty-faced” clones, before rioting and burning down the school.
- “Another Brick in the Wall” is a three-part composition on Pink Floyd’s 1979 rock opera The Wall, written by bassist Roger Waters. “Part 2”, a protest song against corporal punishment, and rigid and abusive schooling, features a children’s choir. At the suggestion of producer Bob Ezrin, Pink Floyd added elements of disco.
