Ringling Bros. Barnum and Bailey

Put it in a one ring tent to give the illusion of biggness. Make it a story book if you must. But don't do this to the Greatest Show on Earth. I remember the center ring act coming in the back, and facing the front, and the end ring acts coming in the front and facing the back. When front track is no longer clearly defined I guess you just wing it and let them line up where the leader choses.
