High School Musical Pep Rally
From Disney's Hollywood Studios Wiki
The High School Musical Pep Rally is a retired mini-parade with some audience participation elements, that featured songs from High School Musical. Hong Kong Disneyland also has a version of this attraction called High School Musical Live!
This attraction usually took place in front of the Sorcerer's Hat on Hollywood Boulevard, but is performed on the Streets of America if the area in front of the hat is needed for one of the parks many Special Events.
This attraction ran from January 21, 2007 to September 8, 2007 and was replaced by High School Musical 2: School's Out only a few days later. Later, that attraction became High School Musical 3: Senior Year - Right Here! Right Now!
