I have to apologize Claire; that is a dance I wrote... jeesh, I can't even remember my own dances anymore.
I posted it to Shared Weight in February of 2014. :"For 20 couples, with many dancers still working on the walking thing, it went fine (1 1/2 phrases seemed to be the right amount of time to get through the middle). Nobody had to leave their partner, and you got to see lots of people. "
I call it circ-splosion in my box. I went back to look for it when Claire asked me about it; and didn't find it. But it was something I made up on the fly.
It was nagging at me, so I did some more digging, and found it.
Hope folks have fun with it.
