 1986, U2 crew member Greg Carroll was killed in a motorcycle accident while running errands for Bono. Bono? Bono. I know. I had to stop myself. Sonny Bono. That was a different guy. That was a different assistant. The song One Tree Hill on the band's Joshua Tree album is dedicated to Carroll, an indigenous Polynesian man Bono first met in New Zealand during the band's Unforgettable Fire tour. Vocals were recorded in a single take because Bono didn't think.
