Just spoke to someone and it looks like this will remain one of those folk mysteries. Doesn't help Sue I'm afraid so maybe she can just publish and be damned :-)

Sorry I can't help further.

One memory I will keep forever is standing chatting to Ted outside the Duke of York in Eccles. 4 or 5 of us, all bearded folkies, full of good beer, when a policeman approached us and asked if we had seen anything suspicious on the car park. We answered in the negative but the policeman pressed us further, as the miscreant he was seeking had been described as bearded. Ted, resplendent in Lancashire flat cap, clogs and full length Arab cape looked round at all of us, winked and asked the policeman if the informant had said anything about a cape. The policeman just shook his head and walked off.
