Swing, jazz and blues - Dance to the music

Here is a terrific up-tempo version of Lady Be Good done by Artie Shaw and his orchestra. In the video clip you also see couples dancing collegiate shag (or possibly some other form of shag).

I spot Buddy Rich at the drums, but who are the other musicans in the clip, can you help me identify them?

What do you think of the video clip with Artie Shaw playing Lady Be Good? Please comment.
