Schoolhouse Rock. If you are a child of the seventies and eighties, then you are probably familiar with the classics: Conjunction Junction, Three Is A Magic Number, I'm Just A Bill. You know the theme song: As your body grows bigger/Your mind must flower/It's great to learn/ Cause knowledge is power! And you know that Saturday morning cartoons weren't complete without Schoolhouse Rocky-- in all of his buff, geeky glory--flying across your television screen.
Schoolhouse Rock: The Official Guide documents the history of the cartoon series. David McCall, president of a top advertising agency, was frustrated that his son didn't know his multiplication tables, yet he knew all the lyrics to his favorite Rolling Stones songs. McCall challenged his jingle writers: write catchy tunes that would help his son and children across America memorize basic arithmetic. The writers weren't successful, but one of them had a jazz musician friend named Bob Dorough. Dorough was the perfect man for the job.
His first composition was Three Is A Magic Number. The song was put on a phonograph and sent to several school districts were it was tested in both urban and suburban areas. The teachers and students loved it. The rest, as they say, is history.
