Due respect and condolences to friends, family and fans of Florence Henderson, who passed today (Thursday, 11.24) at age 82 from a heart attack. Everybody knew her as Carol Brady, of course — the soothing matriarchal figure on The Brady Bunch. Which, no offense, I avoided like the plague.  And which millions of viewers swore by during its four and a half year run (9.26.69 to 3.8.74).  The final episode of that ABC-produced, Nixon-era sitcom aired 42 and 1/2 years ago.
