M.Ted,If you are serious about wanting to perform the kind of stuff you have described here in Shepherdstown, you'll probably want to get in touch with Andrew McKnight. He does the "Shenandoah Coffee House Series", which is the main venue for folky-folk kinds of stuff (as opposed to traditional or derivations on traditional stuff).
His address is:
Andrew McKnight
c/o Shenandoah Coffee House Series
P.O. Box 481
Aldie, VA 20105.
His concerts/coffee houses are generally very well attended. Performers have come from as far away as Maine.Carol
