I'm mostly a lurker on these boards. I play guitar and sing songs around and about - I've been to the Stage Door on Sunday nights quite a lot, for example, though not very recently.
Every year I notice a number of local summer fetes and festivals with music stages and think "I should find out about playing one of these", and then forget all about it until the following summer. So I thought this year might be the year I ask around if anyone has any suggestions or contact details. I could go along and talk to the organiser about what to do for the following year, but this might be quicker (considering I've failed to do that for a few years now).
First one that springs to mind is Mint Street Music Festival, details / contacts are on facebook (depending how you feel about the data-mining activities of course) - that's in July. No idea who organises it but worth messaging them perhaps.
