I've already dropped Sean - or Suibhne, if you prefer - a line to thank him for this recording, which is a real cracker. The fiddle-playing has a wildness to it which really conjures up the vision of demons swirling round Henry's head and pressing him on to the fatal deed. I've only listened to it three times so far, but the tune's already lodged in my head. Go and listen to it. Go and listen to it NOW.
I'm not sure whether you're after written lyrics or audio recordings, Dan, but you can find examples of both at the links I gave in my original post. I'm sure other people here will be able to point you to plenty of other gallows ballads you could sample on-line.
Right: we're off to a great start! who's next?
