BEATLES CARTOONS - COMPLETE SERIES 1965-67. The Beatles exploded on to the American scene in February 1964. In September 1965, the Beatles cartoon series debuted on Saturday mornings. The cartoon image of the Beatles captured their "Help!" era look. As the Beatles' image changed and their songs became deeper and more psychedelic, their cartoon image stayed the same. Seeing the cartoon Beatles play Sgt. Pepper era songs is a little odd but very cool. On DVD.
