''When we were making our third record, the War LP, we were being thrown out of the studio by the studio manager because we had overrun or something and we had one more song to do. We wrote this song in about ten minutes, we recorded it in about ten minutes, we mixed it in about ten minutes and we played it, then, for another ten minutes and that's nothing to do with why it's called '40'.''
The song 'I Fall Down' is about a girl Bono knew named Julie. She's the daughter of a wealthy lawyer in New York, who ended up moving to ireland and becoming involved in the same bible group U2 were in. She later became involved with Pod, a roadie for U2 at the time, the 'John' in the song.
