(bono) wrote this song for the band it was his idea to leave their producer and flee to germany and it was all kinda blowing up in his face and felt he let the band down because recording achtung baby was going nowhere after a full yearin studio they didnt produce one song and he felt responsible for killing the band and this was his goodbye song so to speak to them...now I dont like to spread rummors but I heard him in an interview (bono) say something to this regard
