I've just caught up with this on my return home from Whitby.
It would be great if you could make it to Wareham next weekend!
The Wail is a festival of unaccompanied singing. There are no big names, but a mix of invited singers whom Alan likes, and thinks other people will like, and others who come because they like to sing. There are 3 marquees, with a bar in each, providing different types of song event. One is the Middle Bar's home from home, one is run like a folk club, with floor spots, and one is usually just jump in and sing. There's a mediaeval midnight banquet on the Saturday night (and a costume workshop on Saturday afternoon for anyone looking for suitable mediaeval garb).
