I really must get out more. In the last 5 years I can't remember a single occasion when I heard any rock music or opera at an advertised folk event.

Come to think of it I heard more false American accents in the 60s than I have heard in the last 10 years.

Even though many of the big names on the folk scene are not my cup of tea, nearly all of them at least use traditional music in some way and/or acknowledge their debt to traditional music. I see a very healthy folk scene. The only regret I have is that it it is not as healthy yet in my home city for various reasons, but we're working on it, not shouting the odds from a distance!
