The story is ballocks, the second one that is. MacColl and Lloyd met in London, via their mutual acquainatnce with Lomax. I can't remember the details, but if you consult Ben Harker's Class Act, it is doubtless in there.

Regarding the first story, I dare say there are people in this world who are childish enough to vandalise a perfectly good chair in the way you describe, just as there are people who are childish enough to propagate unsubstantiated legends. But why would a folk club organiser book anyone he thought was an arsehole.

Are you the last man in Europe or something?
