Started more than 50 years ago by organist Katrina Munn and her musical group of friends throughout the Upper Valley, the annual Palm Sunday Choir Festival has become a favorite event in the Bradford area. This year’s festival will be on March 20, at 7 p.m. Many area church choirs, groups, individuals and musicians come to sing anthems. The choirs join together for a combined presentation. This year it will include Mozart’s “Ave Verum” and Gaul’s “They That Sow in Tears.” The high point of the festival are the hymns, lifted up in glorious voice by more than 200 gifted singers, always ending with “All Hail the Power of Jesus’Name.” The festival is now the last of the six Sunday evening Lenten services sponsored by the Bradford Inter Church Council. The culmination of the evening this year will again be Organist John Atwood at the console.
