Long before the Bachelor/Bachelorette, there was the Dating Game. If you won, you went on a chaperoned date (according the the NY Times the chaperone might be Jim or Chuck), usually for a dinner at Catalina Island. Groucho Marx daughter won the grand Kahuna, a trip to William Holden's African safari resort. Groucho asked the questions and picked the date for a father's day edition of the show.
The list of celebrities that appeared on the show is a 60's who's who. Some were celebrities already, others had yet to break through.
Steve Martin twice. He got picked by the ladies both times
Pee Wee Herman
Bill Bixby (was on 4 times) He and Dawson appeared on an episode together
Groucho Marx (he interviewed the guys for his daughter) Hilarious.
The Grassroots: Warren Entner and Rick Coonce
Jim was poised yet retained just the right amount of sarcasm to make him the perfect host for the show.
