Johnny Whitaker,Kathy Garver,and the late Sebastian Cabot guest stars on any OTHER comedy series after "Family Affair" ended? And besides "The Little People/The Brian Keith Show",did the late Brian Keith guest star on any OTHER sitcoms after "Family Affair"ended?

Johnnie W. made an appearance on the 2002 revival series of Family Affair.

Cabot appeared in an Ironside spoof as "Chief Copperside" in 1971, right at the same time as the end of Family Affair on The Red Skelton Hour.

Johnny appeared on Bewitched in 1969. Oh, I just realized Family Affair would have still been in production then.
