After deciding to call my autobiography "Testimony" which was partially inspired by the title of a song I had written years ago, I went back to the original tapes out of curiosity. When I looked at the track sheet I saw: the incredible Gil Evans and his horn section, the guys from U2, Larry Mullen Jr.-drums, Adam Clayton-bass, The Edge-guitar, and Bono-backing vocals, producer Daniel Lanois-percussion, Ivan Neville-backing vocals, Nile Rodgers-wah wah guitar, Bernard Edwards-bass, Bill Dillon-sonic guitar, and myself on vocal, guitar and keyboard. I don't know if I'd ever seen such an extraordinary array of music makers together on one track before.

This musical odyssey started when I was composing the music for Martin Scorsese's movie The Color of Money and asked Gil Evans to do some orchestrations. He ended up doing a horn arrangement to a piece I had mistakenly left on a tape I'd sent him. Not long after, I was off to Dublin, Ireland to do some recording and experimenting with U2. Daniel Lanois was producing their album and mine as well. I decided to bring the 'stray' horn track with me. The boys were all enjoying Gil's horn chart and we decided to play along with it and see what happened. That's Gil counting it off. I began riffing some words Bono helped inspire. He said, "Sing about how you found music, or how music found you."

After it was mixed for my record the track fell into the hands of Nile Rodgers. Nile and bassist Bernard Edwards funked it up. So now when I revisited the multi-track, this unbelievably unique collaboration knocked me over. Today, I'm able to combine all these different worlds into one unified composition, just the way it should be experienced. It's one for the ages, one for the books.
