"When you sing, you have to open yourself up, you have to be raw. And you have to reveal yourself, and sometimes it's very difficult for me to listen to that back, because it might not be as macho as you see yourself."
- Bono, 2002
The song 'One Tree Hill' is named after the highest volcanic hill in Auckland and was dedicated to Greg Carroll, who had become Bono's personal assistant. Greg Carroll was killed in a motorcycle accident in 1986.
