Qualifying what I say Jim, leads down a one-dimension historical track of pedants and borderline asperger's cases (with sympathy to anyone suffering from autism) who aren't satisfied till they get the answer they want to hear and are prepared for an attrition of any length to achieve it. Folk has had limited critical theoretical analysis for a few reasons, one is that people really don't give a shit about it, two you won't get a debate worth a damn that doesn't come back to collection and attribution and three, there are few neutral and intelligent voices - each has some professional or quasi-professional axe to grind. Compared to the debates around folklore, folk music criticism is in the intellectual nursery and this board is pleased to act as nanny.
