Calling While the dancers come onto the floor, tell them a story to keep their attention while they get sorted out, so that you keep their attention.

Maybe demonstrate the step to the band to get the beat right, and find other ways to communicate that don't rely solely on standard terminology. The last tune is important. When signalling to the band, do it as one more time through the tune, not the dance. Tell everyone in the band, not just the neartest person. Wave a foot for the last time.
