When we he ever on SST? I don't remember that.
Either way, I'm really saddened by this; aside from Ron Howard (obviously), I think this only leaves Betty Lynn (Thelma Lou) as the only remaining Mayberry citizin still with us.
Last summer I received a book about Andy Griffith and Don Knotts' decades-spanning friendship as well as behind-the-scenes stories about THE ANDY GRIFFITH SHOW as a gift, and it was interesting to read about Jim Nabors, in that Andy had "discovered" him and felt he would be a good fit for the show, so they brought him on as Gomer (this after they were originally going to give the role to George Lindsey, who ended up playing Goober instead), but then Gomer became such a popular character that Andy and Don felt upstaged by him, so they created the GOMER PYLE, U.S.M.C. spinoff to basically get rid of him.
Then, of course, as Sid & Marty Kroffts' shows began to decline in the 70s, he and Ruth Buzzi starred on THE LOST SAUCER as Fi and Fum, a pair of futuristic androids who land on modern-day (1975) earth and invite a boy and his babysitter aboard their saucer to check things out, but when they begin drawing unwanted attention, they panic and take off . . . with the kids still onboard; naturally, each episode was about trying to get the kids back home to their time, but they always end up on earth in the distant future, or far back in the past.
And I have to say, his is perhaps one of my favorite Season 1 episodes of TMS.
