Golden Tones chorus and Natick High School’s West Street Singers welcome music-lovers to a free, interactive, intergenerational, inspirational concert on Friday, January 31, 2020 at 6:30 p.m. at the Common Street Spiritual Center, 13 Common Street. In this public collaboration between teen musicians and singers old enough to be their grandparents, the two choirs again invite the public to experience the joyful sound that results when two generations of singers blend their voices together. (In the event of “stormy weather,” the concert date will move to Friday, February 7 at 6:30pm.)
