Josh Jones digs up a piece of pop culture history:

The band themselves had almost nothing to do with the show, other than appearing in an odd promotion. Trading entirely in broad slapstick comedy of the Scooby-Doo variety, the show saw the four mates tumble into one goofy situation after another, some supernatural, some musical, some theatrical. Although all natural performers themselves, no Beatle ever voiced his character on the show. Instead, American actor Paul Frees, as John and George, and British actor Lance Percival, as Paul and Ringo, imitated them, very badly. The Beatles cartoon show aired at a time when the kids TV landscape was just beginning to resemble the one we have today, with ABC competitor CBS running superhero shows like Space Ghost, Superman, and Mighty Mouse, but the surreal plots and musical numbers on The Beatles were an attempt to reach adults as well.
