On February 3rd, 2018, at 7 p.m. (note the early start-time), the University of Guelph Symphonic Choir welcomes the Voices of Joy Community Choir to sing a collaborative concert at Harcourt Memorial United Church (87 Dean Avenue, Guelph). Each choir will present music from their repertory, and then the choirs will perform together, with audience participation encouraged. The Voices of Joy, a choir servicing developmentally challenged adults in Newmarket, Ontario, have been warming the hearts of audiences for decades.
