"It's a song about an impossible relationship and someone looking at what's happening. In those kinds of situations, observing and the desire to intervene can poison everything."
- Bono on Stay (Faraway, So Close!)
'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.
