Thanks for the ping.
Following links and watching videos, I find that this is a movement to have these dances all over the world on Easter Sunday. Your group needed to register and the deadline is past. There is a training video for the dance steps. The videos that will come out of these events will be online. That will be something to see. Wish I could see one of the dances, but of course I will be busy with my “traditional” service that day.
