Speaking of rehearsals, the "greats" would meet at Rudy's, discuss what they were going to play, and jam for the recording; you might have one of those records in your collection.
Ray Charles hired a new musical director, who complained because David "Fathead" Newman didn't come to rehearsals. Fathead said "Talk to the man Ray". When Ray sided with the musical director, Fathead walked.
The "greats" don't think too much of "Rehearsals"; unless of course you're talking "Big Band", and my collection doesn't talk much big band.
Enjoy the music.
