The worrying thing is, I can only relate to this stuff if it comes with the right provenance. Provenance is part of the experience; provenance determines authenticity; provenance is the comfort of a higher intellectual authority. If Folk exists at all, then it's only in terms of a Canonical Orthodoxy to which all priests & preachers must be ultimately answerable, even Feral Hedge types like myself who might still be heard muttering in his cups if floor singers are still sourcing from their Steeleye Span LPs.
