Bob Braun filmed a scene on this program for the new Beef 'n' Boards Dinner Theater comedy 'The President's Mistress.' The scene will be shown on an oversized screen in the theater at each performance. The comedy details the problems of an author who writes a book which carries the play's title and then dedicates it to 'J - who taught me to love.' All the women he's know whose names begin with J think he's remembering them and romantic entanglements abound because he is now married to a woman whose name does not begin with J. On a TV talk show, his wife douses him with a pitcher of water. In the seven-minute scene to be filmed on the air, Braun plays himself, Arlen Dean Snyder portrays the author, and Mimi Cozzens plays the wife. The segment will be directed by Bill Leslie, formerly WLW-TV.
