I've seen a person whose name I can't recall perform on the instrument a couple of times at the Chestertown MD. Tea festival, which is every Memorial day weekend in the eastern shore town. It commmorates the town tossing tea into the Chesapeake in sympathy with the action in Boston harbor. he did traditional colonial tunes and also talked about the dangers of lead. He got some incredible sounds out of the instrument. Both the town and festival have web sites if anyone is interested. I think the performer was local to the area.
