Students across Mercer County with multiple handicaps perform holiday music during a bell choir concert at St. Henry Elementary School on Thursday morning. The students are part of the Peace Chords Bell Choir and attend the middle school, high school and transitional classes of the Mercer County Educational Service Center. Students from Celina, Coldwater, Fort Recovery, Parkway, Marion Local and St. Henry are among those in the choir, director Cathy Liening said.
