Saturtainment: An episode of The Beagles (1967)

 Sources say that the first part of "The Man in The Moon", a four part Beagles arc, premiered in March 1967, backed with a King Leonardo rerun.

While the series was itself a parody of The Beatles, whose own licensed animated series was in its 2nd season, Stringer (Mort Marshall) & Tubby (Allen Swift) were actually parodies of Dean Martin & Jerry Lewis. Kenny Delmar is the narrator.

Edit, 10/10/21: The video has been deleted because the YouTube poster lost his channel. In its place is a sample clip:

What killed the show was the fact that at the time, networks didn't program their children's blocks from 8 am to the afternoon, but rather, from 9 or 10 am (ET). The schedule would expand a couple of years later, but too late for The Beagles.

No rating. Just a public service.
