Just an update. It took a year but I found the Folk (or at least Folk revival) folks around here. There's a restaurant called "The Great Machipongo Clam Shack" in Nassawadox, Virginia which is a couple of miles south of me and they have open mics weekly, Thursdays now. Apparently they have had one the first Wednesday of each month for a couple of years.
I went to November's just as an audience member and it was just like being back in a coffee shop in Boston in the early '60's except with a beer license and food. They have a small stage with room for no more than 2 and a PA system. The performers included singer/guitar players, some doing original material most doing covers, a poet, I guess they sometimes have a comedian. To me it was great.
I went with guitar in hand last Thursday. Since there had been an open mic Wednesday though, I became the opening and closing act. No one else showed up. I played for almost 2 hours less a couple of breaks. The patrons took it OK although to fill the time I did every song I know plus some jazz and a little classical. It was much better than my first attempt last spring, which was sort of a disaster due to a host band that insisted on playing along with me although they'd never heard me play before. I'll go back to this one.
If the question comes up again, yes there is music on the Virginia Eastern Shore and we know where it is now.
Incidentally, thanks to those here who offered me support a year ago when I started thinking about performing this late in life.
