One of my earliest memories of any kind is a snibbet from The Beatles saturday morning cartoon show from about 1967. Oddly, for the next 20 years–despite the omnipresence of Beatles trivia–I saw nary a reference to it to the point where I bean to doubt it had existed. Then in the 80s MTV re-ran some episodes and I was vindicated. (I’m fairly certain it had nothing to do with Yellow Submarine, Ranger.)
Also barely-remembered from about that time is a show called “Tomfoolery” or something like that, with a bunch of bizarre animal characters. The only bit I remember is Chicken Lickin’ thinking that the sky was falling because a jigsaw puzzle piece labeled “piece of sky” fell on his head. I’d like to see some more info on that show.
And of course a few years later was The Groovy Goolies and the song “Chick-a-boom” by “The Mummies and the Puppies”. Doncha just love it?
