A rewrite of a first-season episode ("The Reunion"), where the Baldwins invite old classmates, but most of the invitations are returned or declined because of death or illness.
The third and final time the writers rolled out the old "Baldwin sisters throw a party and nobody shows up" plot device. Also used in The Reunion (1972) and The Starlet (1979).
The final scene takes place on Tuesday, June 4, 1946.
Last show of the series it got cancelled because of declining ratings and Earl Hamner Jr felt the series ran it's course and the cast and the crew were ready to move on and do other projects as well.
This was the waltons last season.
