Hello,
I have only directed the full version of
High School Musical; however, in looking at the online descriptions, there are a few songs that are not included in the Jr. version: "Cellular Fusion," "I Can't Take My Eyes Off of You." "When There Was Me and You."(my favorite song in the show), and "Lie to You."). However, the one act version does include "When There Was Me and You." Also, the Jr. version specifically lists the following characters that are not specifically listed in the full version: Drum Major, Mrs. Tenny (chemistry teacher), and Moderator for the Science Decathlon who can be double cast as Ms. Tenny.
As far as which version is best for middle schoolers, Jr. versions are designed for middle schoolers and are also listed as a one act. I have directed other Broadway Jr. shows, and you can make them as elaborate or as simple as you wish. In general, our cast and audience enjoyed performing the show and its songs. I would point out that you do need a full basketball team to do "Get'Cha Head in the Game" well. We did it with a minimal number of players, but it would have been easier with a full "team" on stage."
I hope you find this information useful.
Good luck on whatever you decide to do,
Ken Robinson
