"There's something about performing our songs in front of a large crowd which works. It's to do with the fact that a lot of those people at those shows are there to celebrate not just their favourite band or a favourite band, but actually part of their history and their life and the music that they have grown up with. As much as we're getting applauded, I think people are also applauding themselves and their experience and their life."
- The Edge
A local violinist, Steve Wickham, approached The Edge one morning at a bus stop and asked if U2 had any need for a violin on their next album (the War album). In the studio for only half a day, Wickham's electric violin became the final instrumental contribution to Sunday Bloody Sunday.
