"I am quite happy that the Beatles came and went. There is even a sort of glory in not having it go on forever. There is a complete body of work that went from A to Z and it is all pretty damn good stuff. The one thing I am particularly proud of is that nearly every single bit of it has some good message. I feel fortunate when I look back. Life is not easy, but I've been very lucky - and I'm touching wood as I say that."
