The choral composition was written in 1943 to celebrate the bicentennial of the birth of Thomas Jefferson and utilizes four passages of his writings. The texts, written mostly during the Revolutionary War, were seen as an opportunity to project an uplifting message to the United States during World War II. The work was broadcast nationwide and relayed on short wave radio to the Allied servicemen in Europe.

Sojourner Hodges is the guest pianist. Her music has recently been performed at MATA Festival and the Nautilus Music-Theater/New Dramatists Composer-Librettist Studio in New York, N.Y.; and Opera From Scratch in Halifax, Nova Scotia. She is the music director at First Universalist Church in Rockland; and also plays at St. Francis Catholic Church in Belfast and First Church of Christ, Scientist in Camden.

The Robert Coller Chorale, predecessor to Penobscot Bay Singers, sang this piece 40 years ago at the Crosby High School — now the newly renovated Crosby Center. As per custom, the Mount View Chamber Singers will perform songs from their repertoire, under the direction of David Stevenson.

Admission is $15 for adults, free for accompanied children. The singers are an eclectic group, ranging from a pre-teen to singers in their 80s, with varying backgrounds. Penobscot Bay Singers is a 501(c)(3) nonprofit organization. For more information, visit penobscotbaysingers.com and the group’s Facebook page.
