Mama's family finale...?

I'm not sure if this was part of The Carol Burnett Show, or it was a special, but I distinctly remember an entire episode of 'Mama's family' where Mama ends up dying at the end and Eunice, Ellen and Vint were cleaning out Thelma's house and the show ends with them all together...and once again Eunice decides not to go to Hollywood when offered..

This was obviously before the 'Mama's Family' sitcom was even a thought because they killed off Mama, then brought her back to life for the sitcom.
