I got an email request that might be interesting to explore:

Hi, I don't know if you are interested but I was mooching through random youtube music and I came across: Valravn – Krummi. I know it's not the same but the general flow and tone really reminds me of Ray Driscolls' The Wild, Wild Berry. Is it possible that the odd version he found in Shropshire was actually a tune picked up from the Vikings/Norse area of things? I'm no expert but I thought I'd put my hand up.
