I make no claims to being a good instrumentalist, but I'll play you a danceable version of a Hambo on pennywhistle if we can't find anyone else. You're on your own about finding a partner, though. I can teach the Hambo, but it would take at least fifteen minutes, and I don't think we want to take the time for it at a Saturday night dance.
For those who aren't familiar with the Hambopolska, it is a Scandinavian turning couple dance, with a complicated turning step. The music is in 3/4, but slower and more strongly accented than a waltz.
Now, if you want to do the Salty Dog Rag, I'll be glad to teach that.
