Georgeanna Frasier, director of the King's Clown Troupe, said the kids spend between 80 and 100 hours picking out music for the performance.
She explained that the children brainstorm a theme, and develop it into a performance.
"It's really their message," she said of the teens. "They decide how they want the theme played out."
The troupe has been a part of the Prince of Peace Church for more than 20 years, and has had more than 200 high school student performers. The group has performed in 1,000 congregations throughout the United States and Ireland.
Cotant said his parishioners were very responsive to the service.
"These are committed folks," he said. "No matter who they are, they recognize the commitment of these kids."
