I'm not talking about Yellow Submarine. I'm referring to "The Beatles," an animated Saturday morning cartoon show on ABC. It was a huge hit, of course, capitalizing on Beatlemania. But looking back on it, it really wasn't very well written or animated. And outside of using their music, none of the Fab Four actually had anything to do with it. 

Still, it was a huge hit and as a kid, I watched it every week anyway. It ran for a few years. As the article below points out, Paul Frees - aka Rocky & Bullwinkle villain Boris Badenov - provided the voices for both John and George. Another British actor did Paul and Ringo. Neither sounded anything like the real thing. But it didn't matter, because the songs were the real stars and each cartoon included one of them. 

I think the only other animated cartoon show based on a group was the Jackson 5, which also aired on ABC in the early 70s.
