“Be quiet. Big boys don’t cry.” That line was whispered during the bridge, as it turns out, by the receptionist at the studio where they were recording.
It also turns out they almost threw this song away after first recording it with instruments in a proper arrangement. The original demos in that setting were all erased, as half the band hated it. Instead, songwriter Eric Stewart recorded all four band members singing “ahhs” in a 12 note scale, spliced into a loop. So the background “music” is actually a synthesized 48-voice choir, hauntingly pulsing through the Moog. The wiki entry has all the nerdy details. Go there to learn the story behind the lyrics, which isn’t at all what you think.
