Thanks Diane, an interesting and useful definition, not sure about the dig at Seth though..

If this definition is correct then (returning to the question that started the thread maybe?) the folk revival is an irrelevancy to traditional music as:

"'The tradition' will remain that static body of information that has been quite literally passed down before the irrevocably altered times put an end to the centuries-old process"

I assume this means that no song can ever again pass into the tradition?
