Schoolhouse Rock" is one of those marvelous and brilliant ideas that feel so natural that one wonders why it wasn't thought of before. Many know what it is, and even those who don't at least recognize one of its two most popular songs: "Conjunction Junction" and "I'm Just A Bill." To those who are still puzzled or have an extremely vague memory, here is what the entire series is about. Back in 1972, someone came up with the idea to put educational songs to animation as Saturday morning interstitials on the ABC network. The songs and segments covered grammar, American history, multiplication, science, and money. The show became a smash hit and became something of a pop sensation. The majority of adults today still remember this from their fond childhood days back in the '70s. All 46 of the original "Schoolhouse Rock" songs are included on this 2-disc DVD, as well as a new song about the electoral college. They are divided into the aforementioned subjects and can be played individually, randomly, in order by subject, or in order in total.
