It's not so easy for an artist to retire. Being an artist is not like working at a brick factory. I'm quite sure that Mr. Simon will continue to be an artist. Nothing he can do about it!
Paul is Done
It's so demoralizing that as we grow older, our creativity, talent, abilities go away. One of my favorites has put out a new album rehashing previous successes, and has announced his retirement. Relax Paul Simon ..enjoy your days.
