There was a CD or DVD available at last year's Dartmoor FF with some info and notes. I can't remember who produced it.

I would suggest an email to moormusic@talktalk.net, addressed to Mark Bazeley.

Mark and Jason Rice are both members of the Dartmoor Pixie Band and extremely knowledgeable and able step clog dancers. You would be hard pressed to find a better source for Dartmoor clog.
