This whole thread reminds me of a letter about stop and search in a newspaper just after the 1981 Brixton riots.

The point was that the writer had a lovely village bobby in the middle of rural Norfolk therefore there was nothing wrong with the Metropolitan Police in the inner city.

Most of the arguements seem to bwe based on similar extrapolation. I could give a list of clubs where you would be lucky to hear one trad song in a night and another of clubs where trad was predominant. Pick the list that fits your preconceptions.

Curiously in my examples it is the singers clubs where trad has died out and the guest booking clubs where residents are more likely to sing trad material.
