It's a good bet that any American kid growing up in the '70s or '80s learned some elementary lesson from the seminal musical series Schoolhouse Rock!. Airing from 1973 to 1984 (and often revived), the ABC Saturday morning shorts effortlessly introduced kids to grammar, science, multiplication, money, and American history--three minutes at a time. In one smart, comprehensive 2-disc set, all 46 songs and plenty of extras are collected. The four creators developed the series slowly, a welcome diversion from their advertising agency jobs, and ended up taking home four Emmys over the years. The background material includes 10 audio commentaries and a making-of feature for the new song, "I'm Gonna Send Your Vote to College." The DVD subtitle option is a great bonus for those who need to know every word from such favorites as "Three Is a Magic Number," "Interjections," "I'm Just a Bill," and "Conjunction Junction."
