Christmas at the Organ, our annual Carol Sing, this year at Holy Trinity Catholic Church, 409 Cherry St., Columbia 17512. The Midler-Hunter organ was installed in 1951, upgraded by Columbia Organ Works in 1997, and completely restored and expanded by Peragallo in 2017. The church is beautiful at Christmastime, and the acoustic of the room creates vibrant singing, making the Carol Sing one of the highlights of our year.
