The choir was made up of men from the 369th Colored Infantry (also known as the Harlem Hellfighters), a unit of the New York National Guard. Commanded by Colonel Arthur Little, Sr., the 369th was the first to reach the Rhine in 1918 during World War I.
In 1927, Colonel Little's wife, Mrs. Charlotte Fairchild Little, passed away; four members of the Kentucky Choir and Noble Sissle provided music at the funeral. Noble Sissle was the son of Kentuckians George A. and Martha A. Sissle.
