Another Brick in the Wall Pt. 2

Another Brick in the Wall Pt. 2 wasn't built to be a single. Roger Waters wrote it as a slow indictment of his own school years - then producer Bob Ezrin snuck in a disco groove and a children's choir, and Pink Floyd landed its only number one. In 1980, apartheid South Africa banned it after Soweto students sang it against Bantu Education. Disco beat or government ban - which detail surprises you more? Save this for later.
