I see kids at festivals, shanty sings, etc. all the time. My 18 year old daughter has the most extensive collection of recorded Celtic music I've ever seen, and regularly goes to various group singing activities with her friends. My 14 year old son and I plan to go busking across America as a Harmonica duet this coming summer, performing the fiddle tunes and Cowboy songs he plays. I recently went to a David Grisman Quintet concert, and I was by far the oldest person in the audience (I'm 49). Maybe it has something to do with living in the San Francisco Bay Area( although I'm not sure why that should be a factor), but, this younger generation seems to be turning out all right as far as I can tell.
