TT did have some famous couples, George and Elana Hamilton, William and Marcy Shatner, Stiller and Meara, plus a number of game show hosts with their wives, Bill Cullen, Bob Barker, Chuck Woolery (with JoAnn Pflug), Allen Ludden, Monty Hall, Bobby Van, Jack Narz, Steve Allen, Gene Rayburn, Richard Dawson and even Dennis James. When I saw TT in person in 1977, I saw two nighttime shows with Bob & Ginnie Newhart, Dick & Dolly Martin, and Totie Fields & George Johnson. Totie won $1,500 for the banana section one one show, which I was in. The next day, I managed to get in (they didn't want the same people showing up every day) and saw three daytime shows with Bobby Van & Elaine Joyce, Jack & Wallace Albertson, and Adam Arkin & his wife or lady (don't remember which, heck it's been 30 years). Shame that Bob Newhart hasn't cleared his TT appearances. The shows he was on usually had Dick & Dolly Martin and were funny as hell.
I didn't see a release date for the TT DVD. It's safe to assume it will be out sometime in '09, I guess.
BTW, when you saw TT in person, you had to leave one section at at time. There was only one check writing machine. The section that won the most money left LAST.
