In the light of Gg's apparent wish to construct a postmodernist critique of folk song, I think I should direct readers to the basic wikipedia article on it: -

http://en.wikipedia.org/wiki/Postmodernism

I am most taken by two quotes: -

first "of, relating to, or being any of various movements in reaction to modernism that are typically characterized by a return to traditional materials and forms"

but second "postmodernism refers to a cultural, intellectual, or artistic state lacking a clear central hierarchy or organizing principle and embodying extreme complexity, contradiction, ambiguity, diversity, interconnectedness or interreferentiality,[4] in a way that is often indistinguishable from a parody of itself. It has given rise to charges of fraudulence"


I think Gg has shot himself in the foot in the depth of his pretension.
