Mark,It was pretty much a cross between the classical banjo (with gut strings) from the earlier last century and what Pete Seeger did in Goofing Off Suite plus a rythmic feel that those tunes have naturally from the Celtic tradition from which they sprang. Note for note--like Keith but without a band and the heavy drive that a band might impart. Keith really made it very impressive I've always thought. But I hated to see the Scruggs-tuners go in favor of those strange Keith-tuners. ;-)
