John Litweiler came to Madison to write a piece about Cecil in Madison and it was published in Down Beat. IIRC he attended some ensemble rehearsals and a concert. It would be worth digging out.
When Cecil left for Oberlin, he recommended Bill Dixon as his replacement. When Dixon left, he recommended Jimmy Cheatham. I have stories to tell about all of 'em...............sometime when I have the time. Enough to say I ultimately have negative things to say about Bill and Jimmy, so maybe I won't share.
