Are there people you can turn to now for advice about a new song or album?
In music, no. I rely on the experience and knowledge of what would have happened if I'd brought it to the Beatles. That is the best gauge.
What about life in general?
I have some very good friends. Lorne Michaels and I are pretty close. I can always go for a drink with him – we can talk pretty genuinely. I have relatives, my brother and my wife. Nancy is very strong that way. But music, no. It's very difficult. You can't top John. And John couldn't top Paul.
