Incidentally, I'm passionate about keeping English traditional music alive - or rather, keeping alive the tradition of keeping English traditional music alive. By which I mean, there's no point denying that the tradition is at one remove now - I've never met a ploughboy or seen a top-sail hoisted - so there is a Sealed Knot element to what we do. But the music still rings out - some of the peak experiences of my life in the last couple of years have involved a lot of voices in a little room.

But what that's got to do with trying to stop people moving around with a view to keeping their different cultures distinct... well, nothing, is what it's got to do with it.
