Bob Coltman's WEB OF BIRDSONG gets my nomination.
(Ask Mudcat for a nice thread on it.) It was sung at my wedding,
remembered from being sung around the campfire at East coast
outing-club events in the early 1960s. But I didn't know it was
Bob's until I looked up the thread to post this. Now for the
Mudcat testing: Does anyone know the woman who sang it so well
that I remembered it for 27 years? All I can provide as clue is
that it would have been on the Fork Island park in Lake George, NY,
c. 1963, maybe under the auspises of the Cornell Outing Club.
