Thanks again, Allan and apologies for misspelling your name earlier. Yes, I realise that you were not suggesting that changed lyrics became folk. I was asking the question to point out once again the blurred lines. Our club was pretty much like yours although we had more paid guests.

Good point made by Reggie too. Music and genres change. I would add that they also interweave. If we try to define something rigidly there will always be exceptions and we end up with too many sub-genres. I, for one, enjoy diversity. Because I have welcomed change I have been accused of ruining folk music. Well, if I have, I apologise. But I have gained, and given I think, a great deal of pleasure through it :-)
