Of course there is an ego at work when Paul McCartney goes on stage. That is correct. The audience goes to see him play his songs. He does write some annoyingly banal lyrics, but when he is on song he really is very good. "Maybe I'm Amazed" is an unimprovable love song and the sentiments behind "Yesterday" have never been better expressed either. His ego is an essential part of his tool kit for getting across what he does. It does not make him any less enjoyable for me and anyway, I think he's basically a good bloke.
