"The big change is we are selling advance tickets because overcrowding has been a bit of a problem," said Maureen Woltermann, the chairwoman of the coffeehouse.
The audience will be limited to 85.
The coffeehouse will be offered at 7 p.m. Friday, Oct. 10, at the Bechtel Experimental Theatre of the Washington Center for the Performing Arts. Tickets are $10.
Featured performers include South Boundary, an all-male a cappella group, and Cathy Benedetto.
"She's a coffeehouse favorite," Ms. Woltermann said. "She performs ballad numbers and involves audience participation. South Boundary will perform a variety of a cappella songs."
Also, the Aiken Community Playhouse's youth wing improvisational group will perform, and there will be an open mike.
The need to sell tickets indicates how popular the event has become, she said.
"It's another example of how the playhouse has grown," she said. "This is our fifth season. We never imagined the talent."
For the coffeehouse to continue to grow, it might have to be scheduled for two nights instead of just one, she said.
To make reservations, call the box office at (803) 648-1438. Tickets must be paid for before Oct. 10, or the reservation will be forfeited, she said.
