(Video on youtube. Via mitch diamond.)

Some things I noticed:

• Calls are often at the beginnings of phrases not the ends
• Dudley Laufman does the calling thing where for one time through the dance you drop out: "now you're going to do it without the calls". Unlike at a dance now, it's a sudden drop out and it's only one time through.
• It's footage of several dances set to the music and calls of one dance. You can see bits of petronella and money musk. A little confusing.
• At one point near the end, someone is dancing out of control, stops, looks pleased with himself, then gets a talking to
