When Roy Bailey died recently many newspapers carried obtuaries, in which he was invariably referred to as a "folksinger". They didn't feel the need to explain the term, so presumably they expected their readers to understand it. Of course, since many of his songs were not traditional they were not "folk", according to you, so this is another misuse of the term. However there is clearly no point in trying to persuade you of the meaning of the English language.

We are discussing folk clubs. If "folk" means the traditional music which came from the people, are you saying that folk clubs should present only traditional songs? If that is the case then the rot set in during the 60s boom, because most of the clubs were already including other songs as well.
