It can never be again! Everyone always talks about a good thing coming to an end, as if life was over. But I'll be 40 when this interview comes out. Paul is 38. Elton John, Bob Dylan - we're all relatively young people. The game isn't over yet. Everyone talks in terms of the last record or the last Beatle concert - but, God willing, there are another 40 years of productivity to go. I'm not judging whether "I Am The Walrus" is better or worse than "Imagine."
