well I think it sounds like a rubbish idea.

Whats wrong with having some committment to your material, learning the words (with some thought as to what they mean - like an actor does), thinking about how to present it(perhaps a few words to make it accessible to people unfamiliar with your particular strain of genius) - working out an accompaniment that's in the right key for your voice and doesn't sound a tedious argument of insidious intent, and turning up with your guitar in tune.

being a performing artist isn't a neurotic alternative to being an ordinary human being - it implies a responsibility to the poor sods who've been daft enough to listen.

If its a jam session - fair enough - nobody expects too much. but most folk music is pretty subtle in its simplicity - it will take all the concentration you can give it, and then some, just to blend the instruments even.

anyway thats what I think.
