Folk dancing

I have been reading a lot about traditional british folk dances recently, being most excited by the britannia coconut dancers (There is a great explanation in THIS book which I found in Waterstones bargain bin at xmas and is my new bible). I am thinking of making an A-Z of folk dances but so far have only gathered about half the alphabet...ANYWAY as a bit of inspiration I watched THIS which was brilliant and evocative and made me want to take up clog dancing. Watch it before it disappears!
