Whilst it doesn't fit every folk community precisely Ernest's very accurate description cannot be denied in the vast majority of cases in the UK. I am proud to have been part of the Folk Revival in the 60s when most of us were working class with aspirations and fire in our bellies, but I'm afraid it's true, we're now all in our 60s and decidedly middle class however you want to define it. (And for most of us the fire has gone out!)
