Sorry, again, bad choice of language. A kind of coherent story one could plug into, I guess. Is there a song or two, or style that many people took on and said -- Oh, that is what we can do with this -- and other people followed suit in different regions. Did it start as one or two kinds of sound or ways of singing and/or instrumental accompaniment during the revival, and then alter as people decided to go their own ways, discovered new/old/more appropriate instruments, etc? Did different regions come to the fore at different times, or was there one big rush? Naive questions, I know.

yours,

Peter T.
