According to Florence Henderson, Mom Brady was actually TV's first divorced mom. They just let viewers assume she was a widow because TV wasn't ready for a divorced mom. I don't know if this "counts" or not, since it was pretty much an insider secret! LOL
As for the rerun show, I won't bother to watch it again. But I admit the guy who portrayed Keith Partidge was very good and funny, (constantly tossing his hair and admiring himself in the mirror.) And the guy (yes, guy) who portrayed Edna Garrett was also hilarious. The show could have been good if it hadn't descended into sleaze.
