What Dick asked was is the folk revival an irrelevancy to traditional music?
So what exactly is the point of dredging up lists of trad musicians who may or may not still be performing?
I'm listening currently to re:Masters, the first series of Free Reed archive releases, from which it is relatively simple to identify what has endured and what, currently, has not.
Jim Naughtie's current R4 series The Making Of Music is not presented as 'here is some arcane and obscure stuff that you ought to listen to but as a vibrant chronicle of what has made music what it is today.
The revival at its most positive is a continuation and development of what was worth taking from extant tradition.
It is those 'revivalists' who simply copy from a trad repertoire who are the irrelevancy because that is just not what trad musicians do, whether in the midst of a so-called 'revival' or not.
The 'tradition' must be respected but conventions can, and should, be broken (as Chris Wood said, or something like it).
