In the folk world we are 90% entertainers I would suggest - thank goodness! (and its the notional 10% I personally find boring).

and (OP):

many (most?) people who go to folk clubs to be entertained by music or a music based folk acts (eg. more patter than music) want a good time

I dream of going to a folk club and seeing a performer who just gets on with the songs. The ideal: no patter, no entertainment, no would-be WMC comedians, no jokes, no attempts to engage with the audience. Instead, a few mumbled words (at most) by way of an intro and an attentive audience who don't need winning over because they've gone there to hear the music.
