"What separates U2 from most other people who do this? It is in the show. It's rage. And that's where we started and went."
- Larry Mullen, 2015
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.
