I think this album is it. I don't know how well it will go over commercially, but I think we'll be talking about it for some time. Excellent album cover too.
Its usually the people that can't play "Chopsticks" on a piano that are the quickest to find fault with brilliant musicians. Makes them feel important or something. And it is pompous to suggest to anyone what they should or shouldn't create.
I think anyone who puts their works into the public arena must expect that work to be judged, for better or worse. I'm pretty sure Paul would expect that. It's funny how being old is seen as a benefit in almost every other form of music - jazz, blues, classical, but it doesn't seem to work for pop/rock.
