This 30th Anniversary Edition has two DVD's in the set. Disc one has all 46 original animated songs like "I'm Just a Bill", "Three Is A Magic Number", and "Interplanet Janet." There is also a new song called "I'm Gonna Send Your Vote to College." On Disc two (special features) there are long-lost songs, behind the scenes footage, the "Earn Your Diploma" trivia game, arrange-a-song puzzles, four music videos, Emmy Awards featurette, top 20 countdown, audio commentary, etc.. These are great little songs/videos that teach a lot about history, math and grammar. I loved when these would come on while watching Saturday morning cartoons. Brings back great memories of growing up in the 70's! More information can be found on www.schoolhouserockdvd.com. 283 minutes of total running time. Nice gift for a child!
