JR Monterose told me when he and Jackie McLean were in the band, one night he and Jackie were on the road with the band and broke. They walked by a "fancy" restaurant and saw Mingus eating a big meal inside. They waited and Jackie called Mingus out - Mingus made a move to strike McLean and JR threatened to clobber him with his tenor if he hit Jackie.
More Chicago fest sets - Roy Eldridge /Barrett Deems (playing Roy's features with Krupa and Shaw), Miles, Getz, Lionel Hampton, John Campbell, Ella and Muddy Waters.
Only order I have placed with them. When I placed the order they were $10 cheaper than Amazon but Amazon has lowered the price since then. I got impatient. They seem to be affiliated with Naxos USA.
