Jason Robards SD caller

Watch this before it disappears. At 17:45 Jason Robards teaches the old-time square dance to the song Billy Boy. https://youtu.be/d8uQkyCVWts The 1987 film Square Dance was produced by Michael Nesmith. Later Wynona Ryder teaches Rob Lowe. Anybody know the visit? Billy Boy is effectively played as a march here. It is thought to be from the British Isles. The silly song Billy Boy seems based on the old English ballad "Lord Randall." It came to New England with British immigrants and spread south and west. The movie is set in Texas. Fred Feild
