Buddy Rich firing his trombonist (from the bus tapes)

Buddy Rich had quite a temper. Somebody has transcribed some of these bus tapes word by word. Here is an animation of Buddy Rich and his trombonist, who refuses to shave of his beard. A somewhat strange request by the way, but perhaps this incident is from the 60's?

I heard that bus tape a few years ago.

Brutal.
