Small correction to Leadfingers' post of the 10th. (Yeah, takes me a while to catch up here... ;-) )
It's Mac McGann, not Mat McCann. He and Alan Young still (AFAIK, I haven't been for a while) run the open mic night at the Watermans Arms in Richmond on Monday nights - a great place if you want a real taste of those vintage folk clubs: just a small upstairs room with no PA (yes NO PA!), no bar.
Mac and Alan were on the bill of the first ever live performance I saw, at a school concert in 1966 (including the late great Cliff Aungier, who blew me away). Mac still plays that double-neck acoustic. As I think you know, his wife, the great blues singer Dorris [sic] Henderson (who I was lucky to play guitar with a couple of times), passed away a few years back.
(I already listed my other 60s/70s club memories at length in an earlier post, so I won't repeat them...)
