In 1980, NBC rebooted The New Fred & Barney Show as The Flintstone Comedy Show, recycling the title of the 1972 series that aired on CBS, except this time it was 90 minutes, with new segments, and some lifted from other Hanna-Barbera entries.
For example, there were craft lessons and puzzles, like on Super Friends over on ABC.
Dino & Cavemouse: The late Tex Avery directed these chase shorts, trying to recapture the magic of Tom & Jerry.
Pebbles & Dino & Bamm-Bamm (not shown): The Stone Age sweethearts (Russi Taylor & Michael Sheehan) turn detective, aided by their pals, Moonrock, Penny, & Wiggy, along with Dino, in a riff on Scooby-Doo, who never appeared on NBC. Basically, they rebooted the 1971 series to retrofit the Scooby Formula.
The Bedrock Cops (not shown): Fred (Henry Corden) & Barney (Blanc) are part-time Bedrock police officers, aided by the time-tossed Shmoo (Frank Welker).
The Frankenstones (not shown): Introduced in a primetime special some months earlier, Bedrock's new family of monsters lives next door to the Flintstones. Chaos ensues. Charles Nelson Reilly (Match Game, ex-Uncle Croc's Block, Lidsville) replaces John Stephenson as Frank.
Captain Caveman: Prequel to the 1977 series, and more of an outright parody of Superman, with Cavey adopting the alter-ego of Chester, copy boy at the Daily Granite, where Wilma (Jean VanderPyl) & Betty (Gay Autterson) are reporters, under the supervision of Lou Granite (Kenneth Mars, ex-Fernwood/America 2Night).
The Flintstone Family Adventures: The Flintstones & Rubbles go off on some comic misadventures, much like the original 1960-6 series.
Unfortunately, episodes have been jumbled together in 30 minute increments, rather than the complete 90 minute format. The series suffered from what I like to call "late start syndrome", in that it didn't premiere until mid-November 1980, and that proved to be ultimately costly, as the show was cut to an hour in season 2.
Here's the intro:
Outside the US, the series went under the name, Flintstone Frolics, but used the same theme song, with slightly altered lyrics. Hopefully, we'll have more stuff down the road, provided this doesn't get taken down.
