"Storybook Sqaures" lasted after one season on NBC's Saturday mornings block. It has loads of cartoons and one non-cartoon show with Peter Marshall was the host. The opening that I posted was from 1977 during the special week on NBC's weekday block. It was on what was then called Game Show Netowrk (now GSN) during Elvira's "Hollywood Scares" marathon with "Match Game '90" as a special Halloween episode.
