So far identified: male cellist in front ("with all the teeth showing") is James Heagy. Man in back is Malcolm Davison, Heagy's cello teacher and also  the group's conductor. Beside him is bassist Linda Hamilton. Flutist Eddie Street (wearing glasses) is directly behind the blonde cellist; next boy flutist to the right in the photo had the last name of Whitten; girl cellist (glasses) in the front is likely Paula Mazuski.

Add more names if you know them!
