Like most things that happen with Sabbath, it happened all of a sudden. I was intending on doing some recording, but out of the blue, Sharon called up and said she wanted us to do these gigs with Ozzy. I said that if everybody else was up to it then I would love to do it.
My main influences have always been the classic jazz players who sang, like Louis Armstrong and Nat King Cole and Jack Teagarden.
If the work is going well and it's something that has value with some meaning to it, it gives back a lot.
