The Cheshiremen Chorus will present Holiday Harmony on Saturday, Dec. 20, at 3 p.m. at the Keene Public Library, 60 Winter St., in Heberton Hall.

Hosted by the library, the free concert features the Keene-based Cheshiremen Chorus performing holiday favorites in four-part a cappella barbershop harmony, along with guest quartet UpGray’d. The program includes secular seasonal music, audience participation through a sing-along and a light holiday reception following the performance.

The Cheshiremen Chorus is the Keene chapter of the Barbershop Harmony Society and has been a part of the Monadnock region’s choral music scene for more than 73 years. The event is open to the public, with no tickets or reserved seating required. Donations are welcome.
