I've no idea whether anyone is reading this thread but ...
I was in the MSG upstairs watching Martin Carthy. I think I was 17 or 18 at the time. At the end of the evening, Tom Travers (of Tom & Smiley) invited me back to his flat in Prestwich with Martin who was spending the night there. Back at the flat, out came the guitars & I spent a very pleasant few hours playing blues with Martin. Looking back to that evening I kick myself for not asking obvious questions but in my defence I was just a young plonker.
A few years later, I was helping to run Salford University folk club & tried to book Martin when out of the blue I got a call from Jenks to go see him. Off I went to his upstairs office where we had a very pleasant chat (he was very cordial), the conlusion of which was that Martin could not perform at our club because Jenks had him on an exclusive contract to perform only at the MSG and our club fell within Jenks' domain.
Anyway, Jenks did not hold a grudge because he later booked me to perform with Tony Capstick.
All the best
