Damn - what an appalling few weeks for jazz fatalities. So sorry to hear this - he was one of those guys it was a real pleasure to see live as he seemed to really thrive on small-venue audience interaction/enthusiasm.
I think I caught that Cheltenham performance, Bev. Also caught him at Bath back in the 1990s with Scott Colley (the Georgian Pump Room I think - an appropriate venue for this most civil and elegant of jazz artists). I can remember him saying at that gig that he reckoned he was cut out to be 'a good old guy'. Couldn't agree more. RIP Mr Hall.
