Ray Charles guested; he performed Georgia On My Mind, Busted (his 'own' percussionist, Pete Turre, playing on Buddy's drums) and participated in the finale (possibly doing One O'Clock Jump) with Woody Herman and Buddy Rich*.
Parts of the recordings were edited in Buddy Rich - Up Close, but without any of the guests.
The Drum Channel has promised that more (how much more, and when?) will be released later as The Buddy Rich Show.
2-DVD: Drum Channel, 18 October 2011.
*Details kindly provided by Peter Turre.
This partial audio recording includes Busted (from 1:02:56):
