Spooktober: Halloween on The Facts of Life (1983)

 From season 5 of The Facts of Life:

By this point in the series, Edna Garrett (Charlotte Rae) has left Eastland School, and opened a shop, Edna's Edibles, where Blair, Jo, Tootie, & Natalie are all employed part-time.

In the Halloween episode, a customer disappears, and the girls fear that Edna may have pulled a "Sweeney Todd", and turned the poor fellow into ground meat.

As you can see in the modified opening credits, Pamela Segall (Adlon), now a respected voice actress, had joined the cast, but, apparently had not yet appeared on the show, though that would change with the next episode. Nancy McKeon (Jo) was moonlighting, as we know, heard on The Puppy's Great Adventures over on ABC, and, 20 years later, Mindy Cohn (Natalie) would make a comeback in cartoons (What's New Scooby-Doo?).

The theme song was co-written by the husband & wife team of Alan Thicke & Gloria Loring, and sung by Loring (Days of Our Lives).
