"At the instant we were recording it, I got a very strong sense of its power. We were all playing together in the big recording room, a huge, eerie ballroom full of ghosts of the war, and everything fell into place. It's the reason you're in a band - when the spirit descends upon you and you create something truly affecting. 'One' is an incredibly moving piece. It hits straight into the heart."
- The Edge, on the recording of "One"
