The structure of choirs within the CCC organization has evolved over time. What began as the Junior Choir of the First Unitarian Church grew into a program that consisted of singers from the church and the community. By the mid-1960s, the choir changed its name to the Chicago Children’s Choir and operated a variety of choir units, training programs, programs in schools, and the Lawndale Children’s Choir. The CCC held its first open auditions in 1966, bringing in additional singers from the community. This series documents the CCC units, school choirs, the singers and their parents, alumni of the choir, and other choirs.
