Wareham Wail Sept 4-6 Now called the Wail, cluette as to the unaccompanied genre.

Pennymoor Song & Ale June - it can sell out so be quick. Stewarding unlikely.

Chippenham is almost in June - the stewarding has contacted me already so contact them now.
Upton will be 4 days though the Bank Holiday Monday isn't (a BH). Towersey is a big festival and has moved, they do work stewards pretty hard, but as a steward you do get to arrive early.

I am sure we will bump into each other somewhere, you will spot me.
