Ah Burnham! So you are probably a veteran of the Ritz acoustic club then? To be fair I've always enjoyed the ritz on the occasions I've made it that far. It's a very friendly atmosphere on the whole.
Another good one if you can get there is the Davids Hall in South Petherton, just off the A303 - I think it's the first or last sunday of the month, but it's a great night, and a real treat to play in such an amazing space.
