Vic,
you omitted Muddy Waters, Otis Spann and James Cotton. I don't remember Chris bringing Mahalia over but he had appeared with her at one time.

Yes, all great - but I was only referring to the ones that I was lucky enough to see.
As a six-former, one summer job that I had was on the South Parade Pier in Southsea (circa 1960) and every Sunday night, there was a top trad. jazz band playing there and I had a job in the bar there, but managed to catch quite a lot of these concerts. On the Sunday when it was the Barber band, I finished my shift and rushed out through the empty theatre to meet Tina who had been at the concert and was waiting for me outside. As I walked through the theatre, the orchestra pit piano was being played by Ottilie Patterson. I met Tina and we crept back it to listen to her playing and singing a few songs; I particularly remember "Squeeze Me". Then Chris came in they spent a few minutes chatting to two young star struck admirers.
