"I have never tried to write this thing called a song that's played on radios all around the world, that window-cleaners hum, that people listen to in traffic jams. I was never interested in song: U2 came about through a sound."
'40' from the War album almost was never recorded. The band (minus Adam Clayton who had left the studio) had gone over their booked studio time, but convinced the studio manager to let them record '40'. It has closed many show since. The Edge plays both electric and bass guitar on the song.
