So at last we have our answer.

Folk continues to exist, but in forms that are, for whatever reason, altogether invisible to the Folkies. As long as there Actual Folk there will be Folk Music and Folk Song - likewise Folklore, Folk Custom, Folk Tale etc. - but it would seem this Actual Folk will be of no interest whatsoever to the Folkies to whom Folk is tightly bound construct which must comply with the Nebulous Agenda Ridden Aestheticism of the Revival (which Folkies laughingly refer to as The Tradition) which is, most pointedly, altogether invisible to Actual Folk.

What, for example, would members of the Folkie Morris Ring make of the teams who comprise the non-Folkie North of England Morris Dancing Carnival Organisation?

THEY NO LONGER DO SO.

Let that particular shibboleth be writ on the headstone of the revival when the last of us is passed away & it is finally dead, buried and, one hopes, soon forgotten.
