I heard this group at a renaissance festival in Maryland a while ago. The Pyrates Royale. Below are a couple of selections available on the web including an hour and a half session. Some drinking songs, some bawdy or irreverent ones some humorous.
"Old Maui" a whaler ballad
"Polly on the Shore"
"A Pirate's Toast" a poem reading
The hour-and-a-half session. The audio is a bit weak but a large selection of their songs.
