I am reading a book about the NBC Monitor radio program. Garroway was a major player on Monitor, yet I haven't come across any mention of Van Doren doing It. Seems just about everyone at 30 Rock, and some from outside 30 Rock, did Monitor: Bill Cullen, Gene Rayburn, Joe Garagiola, Henry Morgan, Arlene Francis, Monty Hall, Hugh Downs and others too numerous to mention.
