There was a Beatles cartoon series on Sat morning TV circa 1964-66. It's in the public domain because the owners/producers didn't renew the copyright. I got a set legitimately off the Internet for a reasonable price and am enjoying a well-made series with great graphics and all the original music from "I Want to Hold Your Hand" to Strawberry Fields and Eleanor Rigby.

It rings a bell. I’d have to watch an episode to recall if I used to watch it.
I remember The Monkees tv show.
