Jim you are being silly billy again, wannabe waterson choirs?, nonsense name me a group who was a copy of them, the other harmony groups were very different examples english tapestry, songwainers,wilson family valley folk, please stop talking codswallop. i can only remeber a few carthy clones ,most poeople using open tunings played in their own style.
anyway jim carroll whoever made the rule at the singers club, it was a flawed rule because it meant english or scottsh people could not sing woody guthrie songs at the singers club, what was also ridiculous was that peggy and tom were allowed to sing songs that were not from their cultural background, they were not from appalachia, the whole thing was an exercise in misguided control
