I have gone to The Snail's link, and found that, in addition to his folk club, the Lewes Arms seems to be a nexus of Dwyle Flonging (which seems a laudable and noble endeavor). It brings to mind a question-which I hope will not be interpreted as being critical of this cultural institution.

Many folk clubs, and folk music related activities seem to take place in pubs. Is this typical in the UK?
