Everyone starts out playing for fun. Then, IF success comes along, it can turn out to be playing for the money. Guys like the Stones, I think, end up where the wheel has turned full circle. The larger part of what they do now is for the fun aspect. And, like many people, what else do they know.

I think it was John Lennon who, when asked a question along the lines of fun vs. money, said, "We started out playing for kicks, then it was for the money, and now it's back to playing for kicks again."
