I can tell from some of y'all's posts that there are some real "TV archive hounds" (or would it be "nerds"?) around here.
Anyone remember this from circa 1970, a little CBS spot they ran at Holiday Time?
It was an animated cartoon, of two woodsmen trudging through snow carrying a "two-man saw." The find a tree they want to cut down, but then a bird is heard singing high up in the tree. Other birds join in (but I can't remember if there are any other forest animals involved.)
The woodsmen can't bring themselves to cut the tree, so through the magic of animation, their two-man saw becomes a musical saw, and they accompany the birds' song.
I know they brought it back for at least a second year...
