I grew up watching the Waltons but I never new John-Boy was replaced in the late episodes. Did you?

@Carla Robert Wightman

Huh...

Thought i had seen them all..

@Carla Me too--- I had to look it up, just now. ------Robert Wightman is an American actor perhaps best known for replacing Richard Thomas in the role of John-Boy Walton in the TV series The Waltons. He played the role beginning with the show's eighth season in 1979 until the end of the series in 1981.

@GERRI that makes sense. By '79 i was well beyond the waltons...
