Nancy Kulp of the BEVERLY HILLBILLIES?
Yup! She played the Hoppy the Cop's mother. She lived next door to the Sanfords and gave Foxx the opportunity to use all of his 'ugly old white woman' gags.
There was a 1977 spinoff from Bewitched
. Lisa Hartman was Tabitha! It didn't line up too well with the original series: Adam was now older than Tabitha and a mortal, and both were about ten years too old from when the original series ended.
It occasionally featured supporting characters from Bewitched
(Dr. Bombay, the Kravitzs), a new wacky aunt for the kids named Minerva, and some of the original 'magical' sound effects.
Over all it was pretty lousy.
fans with a sharp ear will recognize the opening lullaby-like music in the Tabitha
opening credits is the 'Cute Little Tabitha' music they'd play in the original series whenever Tabitha was being adorable.
