There are many many volunteers, semi-pros and pros of all ages working hard in the UK on passing on all of the folk music to another generation. This includes a wide umbrella of folk music. If we stood there insisting on the 54 definition it would be dead and buried in a couple of decades.

Don't understand how the last sentence goes with the previous two. If you're not talking about 'passing on' 1954-def traditional songs, what are they passing on? And if they're not passing on traditional songs, how will what they're doing be any help in keeping traditional songs alive?

Personally I don't care about performance styles - three-part harmony, electric guitar, whatever. What I care about is that people continue to get a chance to hear and to sing traditional songs. And it would be nice if we could rely on hearing them at folk clubs - because we certainly can't rely on hearing them anywhere else.
