The thing that makes “Joseph and the Amazing Technicolor Dreamcoat” so interesting for audiences also makes it challenging for the cast.

“The music is everything from country-western to calypso to a pop-rock sound, and other things that go toward the classical musical theater sound,” said Christopher McAllister, executive director of Stage Right School for the Performing Arts and Theatre Company, which will present the musical Friday through Sunday at The Palace Theatre in Greensburg.

“The different song styles paired with the different moments of the musical work with the plot, and it ends up being something that people really enjoy,” he said.

Not only are there many song styles, they come at a fast pace — especially when most of the cast members are playing multiple roles.

“The challenge is that it’s just song after song, so you don’t really get a break,” said Courtney Harkins of Irwin, who plays the Narrator. “You have to be thinking ahead, so that really keeps me on my toes.”

With lyrics by Tim Rice and music by Andrew Lloyd Webber, “Joseph” is a sung-through musical, with songs moving the action along in the place of spoken dialogue

Based on the Old Testament story of the youngest — and favorite — son of biblical patriarch Jacob, it tells of Joseph being sold into slavery by his jealous older brothers, only to rise to prominence in Egypt and save his family and the Hebrew nation from famine.

Jacob had given Joseph a multi-colored coat that plays into the musical’s title.

“The story does ring pretty true to the biblical source through this sense of parable, but it also has elements of humor along with elements of sadness,” McAllister said.

Its themes of intrigue and family drama are universal, he added.

“Stage Right has done ‘Joseph’ before, and it always seems to be an audience favorite, and even an actor favorite, when we do it every couple of years,” McAllister said. “It’s fun and exciting, and the story is great.”

Among actors in the roles of Joseph’s 11 brothers are:

• Alex Hubble as Asher, a Stage Right veteran going back to 2015, with roles in “Fiddler on the Roof,” “Godspell,” “Les Miserable” and “West Side Story.”

• Nicholas Baron as Zebulun, a first-time performer with Stage Right who has worked with numerous other theater companies. His favorite previous roles are the Dentist in “Little Shop of Horrors” and the Leading Player in “Pippin.”

• Joe Hnath as Dan, a former Stage Right student and veteran of its previous professional company shows. He is active in the local musical and film scenes.

Harkins also is a Stage Right veteran who also has performed with Split Stage Productions and Geyer Performing Arts Center in Scottdale.

McAllister is directing the production. A live 11-piece orchestra on stage will be led by music director Matt Thomas.
