Knoxville’s Community Chorus will perform holiday concerts next month. December 13 at 7 the chorus will perform at St. Anthony’s Catholic Church in Knoxville, and at 2 on December 14, they will perform at First United Methodist Church. The concerts will showcase holiday music, and according to Vicki Kaster, President of the Community Chorus, will feature a quartet knowns as “A Thorn Among Roses,” which will perform some more offbeat, humorous numbers. Everyone is invited to attend, and a free-will offering is appreciated.
