There's not really any logic, said theater owner and producer Kelly Jenkins. "It's just a fun show."
Jenkins will come out of retirement to perform "Devil in a Blue Dress" and "Fever."
"Then I go back to the tech booth and do lights," she said.
The more than a dozen cast members also work hard and multitask. They all have day jobs - or school schedules. And they are servers at the dinner theater.
"You have to enjoy it," said Jason Waugh, who by day is purchasing manager for a local plumbing, heating and air-conditioning business.
He's been doing shows at the playhouse for years. He got involved in theater and music when an injury kept him from going out for football when he was a middle-school student.
"It's the adrenaline," he said. "It's a lot of fun."
He's not alone with the fun factor.
Ashley Myers, who recently graduated from Towson University, has been in Washington County Playhouse productions for six years.
"I like to perform, and I like to have a good time," she said.
Katie Williams, a student at Hagerstown Community College, works at the theater simply because it's fun for her.
Fifteen-year-old Brandon Jimenez, Kelly Jenkins' son, joked that he doesn't really have a choice about performing at the playhouse. He's been on stage since he was 3.
Ruth Koontz said getting to know the performers - some of them in reprised roles - is a bonus of attending the productions.
"We have our favorites," Koontz said.
The Koontzes are fans of Lucille, portrayed by Loretta Czerbinski.
Lucille will have her own television show in the upcoming revue. "I'm gonna do a little singing," Czerbinski said. Her songs include a version of the Eartha Kitt hit "Santa Baby" and "Leader of the Plaque" - as in arteries. Lucille also will imbibe some holiday cheer and will be decked - not with holly - but festive seasonal detail suited to the character she created a few years ago.
