There used to be at least two folk clubs in Twickenham, one at the Cabbage Patch, and one at the Crown. We also used to have a session in Henekey's, right on Twickenham junction on Friday nights. There was a club at St mary's college in Strawberry Hill too, and I think someone tried to start one in the Popes Grotto.[For those who wonder about these things, the Pope in question is Pope the writer, not Pope the pontiff.] So it's sad indeed to hear that there's a dearth of folk music in an area I remember with affection. I lived on Hill Rise in Richmond for many years, so I know it well.
Good luck with your enterprise........Giok
