A three-part composition on The Wall, “Another Brick in the Wall (Part 2)” is the protest centerpiece—critiquing authoritarian schooling—with a children’s choir recorded at London’s Islington Green School by engineer Nick Griffiths. At producer Bob Ezrin’s urging, the band adopted a lean, “disco-flavored” groove and issued the track as a single; it became a Christmas No.1 in the UK and topped charts in the US and 12+ other countries, selling over four million copies. The song’s chant—“We don’t need no education”—sparked headlines and later controversies about royalties for the pupils, and the single was banned in apartheid-era South Africa after student protesters adopted it as an anthem. The track remains one of rock’s most recognizable singles and a cultural touchstone of The Wall’s alienation theme
