"We have been listening to the first three Police albums – realising that these records are minimum masterpieces. It's an influence on our album Songs of Innocence. But I think it's gonna be even more of an influence on our next record Songs of Experience."
- Bono, 2016
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.
