That analogy with religion is a good one lamarca -"cradle catholics" and "converts" for example tend to see things differently. The latter tend to get worried about changes, the former might get pissed off at them, but don't see them as a big deal.

And as with religion, you get a next generation from the converts, and that either moves off and tries something else, or it settles in as natives born. That's what happens with the children of "first generation folkies" - if the folk inheritance sticks with them, they can turn it into a real revived gradition.

And think of all those lapsed folkies out there...They'll be back. Once a folkie, always a folkie. Deathbed repentances - "I'm going Mary - quick, send for a fiddler."
