Former circus and sideshow performers Orville and Melba (Robert Dryden and Mercedes McCambridge in two of the best characters in CBSRMT history) are in for a loop when their con job spirit-mediium act is challenged. McCambridge and Dryden's voices are like a steak dinner: meaty and flavorful for the ears. Wonderful job with the script by these two -- but McCambridge is stellar. You can see why she was picked as the demon's voice in The Exorcist during the second act. Close your eyes and think of the possessed Regan.
