Rosie's comment about Dave Jones bears repeating.
Silurian Morris were dancing border long before it became "trendy"...although the style and kit were very different from what they are now...apart from the blacking up of course. John Ks version of the tradition based on his (and I believe Sue Harris') research did much to popularise the style. Sadly, I believe far too many "border" sides just take the easy option. I have been associated with the Ironmen for over twenty years, and it still ammuses me when I see sides dancing one of our dances and calling it traditional. Yes, the moves are traditional, but the sequence is the teams. True of Bedlams, Silurian etc etc. Actually, probably not Silurian on second thoughts. A similar thing seems to be happening with Fenland molly IMHO
