"Some people say that as they get older and/or have a family they mellow out. For me, the opposite is true. "
- Bono, 2002
Starting life as two seperate demos, 'Ultra Violet' and '69', later evolving into 'Lady With The Spinning Head', The Edge improvised a riff that the rest of the band worked with. With said riff, 'One' was born, ultimately changing the outlook of the sessions and more importantly, keeping the band together.
