A musical werewolf

I recently purchased a triple CD set of English folk music called The Beginner's Guide to English Folk, as I would like to know a bit more about this genre that I'm not particularly familiar with. So it was quite interesting to find that one of the songs is actually a song called The Werewolf that appears to be some kind of 'cult' classic. Written by Michael Hurley and recorded by Barry Dransfield on a self-titled album in 1972, it was only digitally released a few years ago. You can listen to an excerpt on iTunes, where you can also find Michael Hurley's original.
