The mazurka in this video is one of the old ones, untitled, collected by Mel Stevens, and available in the Mallinson's
Bal Folk book. As is my wont with untitled tunes, while teaching it to a student, I gave it the title, "Hannibal's Mazurka." I do love my Roman/Carthaginian history, and who are we to deny elephant's in the alps their right to mazurka? For some reason, that landing on the IV chord at the beginning of the B part seems especially touching. Hits you right in the feels.
UPDATE: Yes, I have shaved my head. And, no, I did not realize my legs looked like THAT.
