CAMBRIDGE – The Chorus of Dorchester continues to prepare for its 2023 free and open-to-the-public Christmas concert. This year’s concert is titled “O Star” and will be presented twice during the Christmas season.

The first one is Dec. 9 at 4 p.m. in the historic Christ Episcopal Church, 601 Church St., on the corner of High and Church streets in Cambridge. The second one is Dec. 12 at 7 p.m., on the second floor of the Dorchester Center for the Arts at 321 High St. in Cambridge. An elevator is available.

Formed for the Bicentennial in 1975 by Cookie Brohawn, this is the 48th consecutive year of concerts being presented by the all-volunteer, 70-voice chorus of singers representing Caroline, Talbot and Dorchester counties. The music of Randall Thompson, Johann Sebastian Bach, Johann Pachelbel, John Rutter and many more composers will be heard in voices of soprano, alto, tenor, and bass, piano, organ, violin, guitar and percussion.

The group is under the direction of founder Cookie Brohawn. Veteran piano accompanist Laura Todd is with the group again this year.

“Every member of the group sings and performs purely for the love of it,” a statement from the chorus said. “Come join us to begin your Christmas celebrations. All are welcome.”
