Folknacious. You can take it from me that Billy Bragg doesn't know the first thing about Padstow carols. That became blindingly obvious from the broadcast. Ditto for the Unthanks.

Interest? Enthusiasm? How is it we never see these people at traditional customs when there's no tv cameras about?

Just for the record, if that dig about 'self-appointed expert musicologists' was aimed at me then you're even further off beam than I thought. I am not a musicologist, self appointed, expert or otherwise. Folklorists certainly interest themselves in traditional customs. It's hard to imagine many musicologists doing the same.
