Jay's off-stage mic was out of sight of the audience. When he wasn't visible on the trading floor, he was in an enclosed, out-of-sight announce area. When shows featured zonks that required him to be in costume, Jay told me he would over-dress - layer the costume under his sport jacket and pants. The show's wardrobe mistress acted as his dresser during tapings, helping him in and out of clothes and costumes, often while he was reading prize or product copy. I, and other collectors, have video of Jay being helped into a costume while he's reading - it's part of a making of LMAD documentary.
