There's an old Beaker tradition (which I believe, though Eileen would never admit it, she stole off the Celtic Christians) of dancing around in circles. She refers to protective actions, marking out of sacred space, the symbol of perfection, etc etc etc.
Just a little hint, though. Having marked out your circle, lined up the dancers, arranged the Quire and set everybody going - try and make sure they all face the same way. When the anticlockwise group slammed into the clockwise one, it caused some fairly severe bruising.
