Well personally, I always preface my performance a folksinger by saying:-

Look chaps, we're in an English folk club. That means an intelligent sensitive audience....people who realise we're trying to show respect for original the text and feeling behind these wonderful old songs. That presupposes a certain degree of sophistication and education.

Not much chance of left wing oiks and johnny bloody foreigner, I know my rights twits barging and shouting the odds. If they do turn up - we tell 'em to bugger off home and watch Simon Cowell dancing on ice with homos, or drinking rum and doing limbo dancing.

And I think that marks out the territory well enough - without giving offence to anyone. how else will we hang on to the BBC Folk Awards?
