The series premiered on ABC on Saturday, September 25, 1965 at 10:30 am.  Each show was a half-hour long and consisted of two "adventures" and two sing-a-long songs.  Lyrics were flashed on the screen so that viewers could join in.  The show was an instant success.

The show was produced by King Features Productions.  The voices of the Beatles cartoon characters were supplied by voice actors Lance Percival (Paul and Ringo), and Paul Frees (John and George).  Animation was done overseas at TVC of London and Astransa, an Australian company.  TVC is also the company that produced the animated movie "Yellow Submarine".  The scripts were relatively easy to develop, as the episodes were based on popular Beatles songs.

There were a total of 39 episodes made.
