Nothing there to convince me, Suibhne. Holding a top C for five as opposed to four seconds could be classed as a 'different interpretation' by those interested in counting angels on pinheads, but I'm talking about a completely different class of variation. 1970s jazz-rockers reprising their own back catalogues don't hack it either.

"(in the Folk Terms you mention)"

Which were the 'Folk Terms'? And why the capitals?

"Folkies get exited over collected specimens"

More pejorative generalisations. I get excited about songs, about live performances, about recordings. None of them is a 'specimen' in my book.
