I went to a birthday party for an old (and older) friend last week where someone sang a Pete Seeger song I hadn't heard before, and that I want to learn. The chorus went:

Then all of life is like a tune
It sounds so sweet but ends too soon
You'd better rosin up your bow
Before it's time to go.

I tried a digitrad search here and a Google search outside Mudcat, and both failed. Anyone recognize this song?

Many thanks!
