Sounds like you caught a great show. Its a shame Billy Joel stopped writing, what a talent.

I knew he was a big fan of the Rascals because he was in a copy band called the "Hassels" where he played B3.
One of the best shows I've seen was the Rascals Reunion tour at the NJ Garden State Arts Center. They can still kick a**.
Wish I could of caught them in their early days in a small club like Donny did.
