A bit of thread-wobble which nevertheless seems appropriate here in view of above post. One of most influential songs of the Revival was Margaret Barry's wonderful, heartbreaking rendition of She Moved Thru The Fair, which everyone, but everyone, was singing in fine traditional style in the late50s-early60s [despite its traditionality being disputed, whatever Wiki sez]. When ultimately asked in an interview [by Karl Dallas if memory serves, but if not I beg his pardon] where she had learned it - on the road? from parents? from other travellers? - she replied cheerfully, "Oh no, I learned it from a gramophone record by Count John McCormack".

Incidentally - more relevantly perhaps - re above post: isn't it a bit over-dismissive to call Rambling Jack & his buddy Derroll Adams, or even Dean Gitter &c, who were indeed Americans and so singing from their own tradition, fake cowboys and cottonpickers - Rambling J had after all travelled with Woody in his early days?
