A calypso carol, a Shaker hymn, a Spanish lullaby, and a Nigerian Christmas song that will have audience members rising from their seats to become part of the performance are on the program for Sunday's concert.

Sponsored by the Port Townsend Friends of the Arts, the program of seasonal world music is family-friendly and sure to appeal to a broad audience. The Wild Rose Chorale, a hometown a cappella group now in its 11th year, will be joined on stage at times by the Port Townsend Youth Chorus, the Port Townsend Vocal Ensemble (high school singers), and 50 community members. All of the musicians combined have rehearsed the Nigerian carol "Be-te-le-he-mu" with African music specialist Sue Williamson of Seattle.

Williamson, who has led workshops for "Be-te-le-he-mu" across the country, praised the Port Townsend performers for being the least movement-inhibited group she had ever worked with. With her assistance, the group developed its own unique and winning interpretation of the Nigerian classic.

"This concert really is all about community, in the best sense of the word," said Wild Rose director Rebecca Rottsolk. "The participants are multi-generational and the music reaches across national and international borders.

"And then bringing so many singers together to learn "Be-te-le-he-mu" was an incredible experience," Rottsolk continued. "We can't wait to present this amazing piece to the community."

The Wild Rose Chorale is also proud to perform the public premiere of Port Townsend composer Chris Hawley's arrangement of "Puer Natus," an ancient Latin carol.

Along with "'Tis the Gift to be Simple," and "El Rorro (Rocking the Child)," the program will include plenty of traditional favorites such as "O Little Town of Bethlehem," "O Christmas Tree," and several familiar audience sing-alongs. Suggested donation is $7.

Wild Rose Chorale members are Roger Aue, Paul Becker, Sally Chapin, Chuck Helman, Marj Iuro, Glen Koch, Leslie Lewis, Glenn Lyons, Lynn Nowak, Shelly Randall, Rebecca Rottsolk, and Al Thompson.
