The group is performing Pump Boys and Dinettes, a musical about four gas station attendants and two sisters who own a diner.
The show is set on Highway 57 in North Carolina somewhere between Frog Level and Smyrna.
The songs range from country to rock and roll and gospel, and all the actors play their own instruments.
"The boys and girls are the band," said director Debra Gillingham. "The guys play guitar and piano and the girls do all the percussion. Not necessarily on percussion instruments, pots, pans, etc."
The show was nominated for a Tony Award for Best Musical in 1982 and ran for nearly 600 performances on Broadway.
"There's no big heavy plot," said Gillingham. "It's all about fun, family, life in general, work at the gas station, work at the diner, customers, love. It's a light-hearted evening of just fun and music. It's not really your typical book musical. It's really more of a musical review, but there is dialogue that ties all the songs together and you start learning about all the characters individually from the very first song."
