Couple of points:
1.There WAS a Folk Club in Weymouth. It closed years ago, (suffered from 'singing to the chairs' syndron).
2. It's Portland that has the Music lisence problem.
Otherwise the houses around the Weymouth/Portland area are definitely getting expensive £70,000 and rising. Portland is a lovely place to live - just remember that despite all the defence schemes Chiswell is very definitely a flood risk area, so either keep your flood board in a good state of repair, just in case; or live higher up.
