On the 2nd episode which opened a week with Patty Duke and John Astin, there was a lady with gorgeous hair who came in as defending champion. She lost this game to a plain lady. As the 1st episode was from a much different week with different contestants, BUZZR is skipping around in the weeks and not going in order. What celebrities were in the week before Patty and John so I can look out for her when they are aired again? The episodes that just aired will encore at 11PM tonight.

If the listings are correct, Patty Duke Astin and John Astin actually appeared together on 4 different weeks.

I didn't realized that John lost a bit of hair. I guess he wear a wig on shows of that time frame, Love Boat, Murder she wrote, etc.
