In the album version of The Wall, "Another Brick in the Wall (Part 2)" segues from "The Happiest Days of Our Lives".
The song also features a choir of schoolchildren singing in the second verse: as the song ends, the sounds of a school yard are heard, along with a Scottish teacher who continues to lord it over the children's lives by shouting "Wrong! Do it again!", and "If you don't eat yer meat, you can't have any pudding! How can you have any pudding if you don't eat yer meat?!", and "You! Yes! You behind the bike-sheds! Stand still, laddie!", all of it dissolving into the dull drone of a phone ringing. It trails off into the next song, ending with a deep sigh.
Gil Potter was responsible for achieving the marching hammers imagery seen in the music video, a tough feat at the time. Potter also worked on Scooby Doo and Yellow Submarine (1968) among others as a cartoonist.
Producer Bob Ezrin had immediately recognized the hit potential of this song, but it took some maneuvering behind the band's back until "Part II" took its eventual form.
