Billy Joel is going to play one show a month for the rest of his life at Madison Square Garden. He already has four shows scheduled, plus New Year’s Eve. But at a ceremony today at the Garden, GOVERNOR Andrew Cuomo–yes, the Governor– came to help announce this new unprecedented residency. What is this all about? I don’t know. Billy obviously has a lot of spare time on his hands. Can he fill the Garden with that many shows? Probably. I think it could go on for two years. ‘Forever’ is a long, long time. In time I’m sure he’ll add guest stars, etc. And he has plenty of songs. Sign me up!
