Free holiday concert! The all-volunteer, 60-voice Chorus of Dorchester will perform its 48th season of wonderful holiday music.

This year the selections range from Bach and Handel, to moving spirituals, to contemporary favorites. The Chorus is under the direction of Cookie Brohawn, accompanied by Laura Todd on piano.
