"I do not think the songs are very potent, I never thought of Zooropa as anything more than an interlude... but a great one, as interludes go. By far our most interesting."
- The Edge on Zooropa
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.
