TOD - the closest I've ever been to a seance was serving as dresser for a friend of DR Elmore's and mine when she played Monica in THE MEDIUM. She had a pretty quick change into a gauzy dress and the diva playing the title role shouted "Velcro!" like "Plastics!" in THE GRADUATE. So, DR Elmore and I dutifully applied Velcro to Loyce's dress and during the seance scene, while I was helping her with her change, the fabric stuck to itself in all sorts of unintended ways. I suggested that the contralto stick to her singing and let us deal with the costuming. IIRC, the Velcro came off before the next performance.
