I was going to comment here but then noted that Jim Carroll had absolutely nailed it in his posting of 13th Feb.
One of the biggest problems that exists in the understanding of music is a phenomenon called, 'misidentification'. This is where the listener, not fully understanding what they are hearing, does the natural thing and compares it to what they do know about. The problem then arises when they follow this up with a value judgement based on the application of their lack of knowledge to the situation. I once made the mistake of taking my father (an opera buff) to a shanty festival. He simply hated it because he couldn't apply any yardstick to understand what he was hearing. I guess that's where most 'folkies' are on this thread. I actually quite liked the 'Miller of Dee' track although Bartok would have been a better arranger being less cautious in his accompaniment I suspect. Actually, I'd just like to point out that Most composers who arrange English folk-song tend to be a lot more respectful of their source material than the folk enthusiast gives them credit for. Even the talented Jim Moray's mixes do not shatter any real barriers and, compared with the Butterworth 'English Rhapsody' mentioned by Jim C above, young Mr. Moray's work is nearly traditional.
