This is the kind of discussion that keeps me coming back to the Mudcat. I never even knew about the black shape-note tradition, so thank you, Guest-whoever-you-are, for pointing it out. I love shape-note singing, and I'm a Jewish kid from Philadelphia, so go figure. Unfortunately, the opportunities to sing shape-note here on the Big Island of Hawaii are vanishingly small, but that's part of the price one has to pay.
By the way, Guest One and Guest Two, it's easy and free to register as a member of Mudcat. Come on in!
