Billy Joel duets with Jimmy Fallon, talks new Sirius radio channel on 'Tonight Show'

Billy Joel -- a very famous New Yorker, after all -- arrived at the new New York-based "Tonight Starring Jimmy Fallon" to effectively consecrate Fallon's Gothamized version Thursday night, and did so by breaking a little news, about a forthcoming Sirius channel -- and by singing a duet of that old Solomon Linda chestnut, "The Lion Sleeps Tonight," with the host.

Of the Billy Joel Channel, he admitted he didn't entirely know what he was going to do with it, but that's OK -- it's his channel to do whatever he darn well likes.

Plus, some talk about WLNG -- a Sag Harbor station you likely know well -- and the fact that the stage of MSG is built on springs.

All interesting. Here are the clips.
