Vocals - Milton Nascimento
He's a Brazilian singer, composer and guitar player with a way of writing, lyrically and musically, that speaks to all people.
Drums - Roy Haynes
Anything we wanted to do, we could do. If he was on drums it would groove, it would have depth, and it would be joyful.
Piano - Herbie Hancock
Every time I've seen him play, or had the honour to play with him, you get this feeling that he is listening and trying to bring the best out of everyone.
Saxophone - Wayne Shorter
I love his music so much. Any music that we're doing, I think would be absolutely blessed and raised to the highest calibre with his involvement.
Trumpet - Clark Terry
I would ask him to do some mumbles somewhere in the song or concert. He is a person who glorified the concept of telling a story without any words.
Trombone - Bob Brookmeyer
He could play trombone and arrange the compositions. That would be really cool.
Guitar - Prince
He's one of my favourites, so I need an excuse to get him up on stage too. I supported him once and it was thrilling.
