Hmmmm. . . that quote from Rolf Cahn bothered me. I DO like to sit (with two friends in particular) and sound just as much like the Carter Family (Little Moses and a lot of other things they did) as we can, thinking that if we can get the letter of the song right, the spirit will somehow descend on us. And sometimes it has. We do this more for ourselves than for an audience (usually this is in our own living room) and maybe that's the difference. Old time music (what I do most) is a participatory sport IMHO.
