 One of the greatest drummers of all time. But you got a lot of interview footage with Chuck Conner, that amazing drummer who was the key to that sound. And I think that was part of it, too. The music was so... It was next-level music in terms of just its intensity. And that's the thing that I think... People can say Elvis and Chuck and Jerry Lee, and I love all those guys, but my God, he was just at another level. And Chuck, I thought, was really the key to that.
