Interesting thread. I agree with the comments about the Fylde festival - good one. We have the Chester Folk Weekend in our village every Whitsun, and its hard to beat. The focus is one of the local pubs, with a few acres of land where marquees are set up for the more formal sessions, and camping is readily available. All the pubs are full of music, and you can have a great time in the most informal surroundings. We've had the beast of the British folk scene there for many years, and long may it continue.
