The Dorchester Folk Club !! That brings back memories ! It was in a pub called "The Chequers" going down towards the bottom end of the high street---it was in a room upstairs,as I recall (1964-66).
             Of course, the Yetties then were based in the Yeovil Folk Club,which was in Half Moon Street,in the eponymous pub--at least one Yeti, (Bob ??) was a dustman in those days,and could be seen going around Yeovil on the back of the Corporation Dust Cart ! Biggest moment for us was having Paul Simon as guest in ,I think,1965.But I don't recall them singing that song in those days --I asked Tony Rose for the words some time later ,well probably 1968-ish,in Plymouth,and he sent them to me (nice man !).
             At that time ,also,the Weymouth Folk Club was in the Fountain Hotel,on the seafront, so,what with those three,and The Forge in Sidmouth,where I used to stay at weekends (in The Winter Gardens,corner of Fore Street, now "Brown's Bar" or something weird),we were spoilt for choice ( there was also the "White Post" at Marston Magna, and ANOTHER Folk Club in Exeter).
Happy days !
Roger ( "Robin & Roger", 1964--66) !!!
