For this "music" challenge entry, I have chosen the "Four Jills", a singing quartet from my (former) home town of Eliot, Maine. Members of, and sponsored by, the John F. Hill Grange, they formed under that name in the spring of 1964 (though they were singing together the year prior). They participated in numerous events in town, including performances at the Grange, the High School, the East Eliot Methodist Church (where 3 of the 4 girls attended services), and the Girl Scouts (of which they were members). They would also enter into Grange contests within York County, as well as the state.
My Aunt Sharon (on left) would pass away in 1977, and Christine (far right) lives in PA, I believe. The two in the center of the photo, my mom and Debbie, both live in the town where they grew up, and actually still sing together, in the church choir.
Below is a clipping from a digitized local paper (dated 20 Aug 1964), with another picture of the quartet.
