about 1978, went to a big folk club in Birmingham (UK) and saw a band called Brownsville Banned, who were interesting, mainly comedy but very entertaining.
The did a version of Sex pistols' 'Pretty vacant', their version was called 'Sissy bankclerks', and it was played on an acoustic guitar (thru a distortion pedal, and on a small junior drum kit - and it sounded absolutely brilliant !!

However, the funniest thing was watching all of the traddy jaws drop open in shock - it was hilarious - the applause were modest, apart from the huge cheers from those of us that saw the irony!!

What folk clubs need is more broad-mindedness, not less, as seems to be the case of late.
