Everyone likes this "dance" — teens, families, adults — it really brings out playfulness!

Talk to the band in advance to explain how things work, and decide whether you'll signal them to start and stop the B part or if they'll pick those times themselves. Ask them to pick a tune they'll be happy playing for a while. They don't play during the A parts, then they play four potatoes to start the B parts, then they cut off at an unexpected time, and it all starts again.

Teach the two lines of the song (you can hear them in the video below) and walk the forward and back while singing. Explain what the wolf does, and emphasize what the pig's partner does — "When the wolf takes your partner, step back out of the set, go to the top, and become a wolf." I suggest that the wolves not forget the tasty pigs at the top of the set (so people don't get stuck at the top).

It's fun to make the A part unexpectedly long sometimes and unexpectedly short sometimes.

I like to add extra wolves after a while — I get the attention of one of the top people, point through the arches, and say "go!". And then their partner.

The dance comes originally from Latvia, where it's called "Savas acis izraudāj" ("Cry your eyes out"). Here's a folkloric version; I wonder if they also do it in a looser style more like ours sometimes?

Thanks to Bob Walser for bringing it to our community; here's his writeup.
