The industrial north. I think any original tradition was flushed away by the massive population movements out of and into the area during the industrial revolution. Indeed perhaps before that - even before industrialisation it wouldn't have neem an area you'd want to have spent any more time in than was absolutely necessary - poor soil, heavy rain, steep hills etc. The Romans seem to have been wise enough to have left most of it alone. I doubt that the natives ever had time to sing play or dance - too busy trying to scrat a living.
I played in the Lancashire tradition and still aren't averse to decent "lancashire" dance tunes but the other stuff that went with them (I can play a rousing version of Gathering Peascods) just seemed a bit false.
Fact is, at the sessions I now attend the music's 99% instrumental and I'm not obliged to pretend to be dewy-eyed by songs about things I have no experience of - either in rural England or Ireland. I like it that way.
Thanks for your offer though, it's very good of you.
