The biggest challenge in Musikmaker's production High School Musical — is getting the whole cast on stage.
Producer Maureen Cruickshank said there was loads of interest in the show at casting in early February.
"There was lots of talent. We had to break a few hearts, but there will be more opportunities. It's been 12 years since the original Disney movie which led to the stage show. High School Musical is like a modern version of Grease, a bit cleaned up. It is up-to-date with things like social media, texting and checking-out on Google which are common to today's teenagers."
In all 38 performers aged 13 to 19, along with two grown-ups, school drama teacher Ms Darbus played by Leona Lenora Robinson and coach Bolton, Scott Chaplow, will cram Riverlea's stage with song, dance and fun.
High School Musical is set in the East High School, Albuquerque, New Mexico, and is launched with a spectacular performance by the school's cheerleaders in support of the local Wildcats basketball team.
