"Something happens when we play together. It's impossible to copy. Every band follow the drummer. We don't follow Charlie. Charlie follows Keith. So the drums are very slightly behind Keith. It's only fractional. Seconds. Minuscule. And I tend to play ahead. It's got a sort of wobble. It's dangerous because it can fall apart at any minute."Bill Wyman talking in the second part of the Rolling Stones documentary, Crossfire Hurricane.
