That's not Bobby Rydells drummer. He was an older guy named "Jerry" who was also his Conductor.

Hal Linden (Barney Miller) carried a piano player with him , a real old guy named Howard Salat. When I was watching the movie "Death Collector", that's the movie that Joe Pesci and Frank Vincent made their first film appearance in I noticed in the credits "music by Howard Salat".

This guy also did the music for a lot of early porn films.... I forgot to ask him if he ever met "Johnny Wadd"
