"If you look at the cover of The Joshua Tree you see 4 very unhappy men.What nobody realizes is that it was minus 20 out there.We were freezing! Put any bastard out there and see if he's happy."
- Larry Mullen jr.
'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.
