It was fifty Thanksgivings ago - fifty years ago...on Thanksgiving.
This little bit of nonsense, set in the bucolic Stockbridge, Massachusetts, was a staple when I was "coming of age." Law enforcement is the butt of the minor joke, the draft being the actual target of Arlo Guthrie's ire. Thanksgiving 1965 (which is when the Massacree occurred) was on the leading edge of a very difficult time for America. Arlo's wry observations are in the best tradition of the age.
If you have twenty minutes give it a listen. It is a Thanksgiving tradition that can't be beat.
