We do indeed go to selected folk group events - we'll be going to one next weekend. It will cost us the sum of £30 for the two of us (Thursday to Tuesday.) It is a small event but there will be workshops, fairly sedate ceilidhs to a live band every night, a singers room and workshops during the day with instruments to borrow so you can have a go. It probably wouldn't be to everyones taste but we find it very relaxing and friendly. You do need to take your own booze as the venues aren't licenced.
