is a musical based on the 2006 Disney Channel Original Movie High School Musical, with music and lyrics by Matthew Gerrard, Robbie Nevil, Ray and Greg Cham, Drew Seeley, Randy Petersen, Kevin Quinn, Andy Dodd, Adam Watts, Bryan Louiselle, David N. Lawrence, Faye Greenberg and Jamie Houston, and a book by David Simpatico.

[2][3] At East High School (in Albuquerque, New Mexico) ("Wildcat Cheer"), Troy Bolton tells his Jock friends, Chad Danforth and Zeke Baylor, about meeting Gabriella Montez on New Year's Eve during winter vacation on a ski trip.

Gabriella, who has just moved to Albuquerque, also tells her newfound Brainiac friends Taylor McKessie, Kelsi Nielsen and Martha Cox of her vacation.

One-half of the song is during the flashback, then we return to East High where Chad, Taylor, Kelsi, Ryan, Sharpay, Zeke and other students sing of their New Year's Resolutions.

Chad interferes, telling Mrs. Darbus that Troy cannot go because they have basketball practice after school and that they have an upcoming championship game.

Discovering that Gabriella was a very intelligent Brainiac at her old school, Sharpay prints her newfound information and puts it in Taylor's locker.

After the auditions have been declared closed, Gabriella and Troy sing the song as Kelsi intended it - much slower ("What I've Been Looking For (Reprise)").

Sharpay is furious, believing Troy and Gabriella have stolen the lead roles and broken the "rules" of East High.

Though most of the school agrees, lyrical chaos erupts during a lunch break when students begin telling their secret obsessions outside of their cliques ("Stick to the Status Quo").

Jack Scott recaps events before Troy and Gabriella dance on the rooftop garden ("I Can't Take My Eyes Off of You").

Troy goes to the theatre and tells Gabriella that they were set up and he didn't mean what he said and sings to remind her of New Year's ("Start of Something New (Reprise)").

Sharpay and Ryan perform their callback song ("Bop to the Top"), which at the same time happens with the basketball championship and the science decathlon, during which Taylor engineers an electronic meltdown in the decathlon and light malfunctions in the game, which forces all the students to move to the theater.

The end of Act II brings us to the gym where all the main characters wrap up their plots (Chad asks Taylor to an after-party, Zeke gets Sharpay to be nice to him, Jack Scott and Kelsi flirt, and Sharpay makes up with Gabriella and Troy).

The students celebrate ("We're All in This Together (Reprise)") followed by a recap of all the major songs in the show ("Megamix") during the curtain call.
