Now, if he really doesn't want to do anything anymore, fine by me--I've got his great albums.
I think he's reaching that point, or close to it. That's probably why he's been cutting back his schedule. Which is the best thing for him *if* that is what he wants.
I'm not going to lie...selfishly, I would like to see him continue on with concerts, as I'd like to attend another show. I want another album, too. However, if that's not what he wants to do, then he shouldn't be forced to.
