Roger the Skiffler

I assumed you were referring the the sixties when I was involved in PR for the band.
Chris and Harold Pendleton launched the Marquee in 1958. As Chris states in bis autobiography he wanted a place to play in London which wasn't the 100 Club. He didn't like the place as the acoustics were so awful.
By the time you saw him at the 100 club the marquee was putting on pop crap lie the Who etc.

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.
