I didn't see the show (dutifully attending 2nd grade at the time) but, my back issue of TV Guide for that date lists both him and Michael Landon as guests. Abby Dalton and Janis Paige were also on the panel. The other celebs (Glenn Ford, Jim Backus, Wally Cox, Charley Weaver and Shelley Winters) are now deceased. That date was a Monday.
