I purchased this DVD late last year for my wife, who is a 6th Grade Language Arts teacher. As useful as it has been for her in her classroom as a teaching aid, I think I've enjoyed it even more watching it with my own kids. As a child of the 1970's, I grew up eating breakfast cereal in front of the TV on Saturday mornings and Schoolhouse Rock was a big part of that experience. The catchy tunes are just as contagious now as they were then and all of the great classics are here - "Conjunction Junction", "I'm Just a Bill", "Mr. Morton", and way too many others to name. There are around fifty in all, including Grammar Rock, Multiplication Rock, Money Rock, Science Rock, and America Rock, all organized by genre and with a robust menuing system that allows playing back individual songs, all songs by genre, or the entire collection. They're all here. Also included is a new Grammar Rock song not previously released as well as an entire second disc of bonus materials. If you loved Grammar Rock as a kid, you likely will find that it is just as enjoyable today, evoking fond childhood memories long-forgotten. This is a classic is a must-have for my DVD collection.
