I am looking for a song that I learned at camp when I was a kid. The song was about the revolutinary war. The words I can remember are:

In a little valley, by a bridge they made their stand.
Just a bunch of boys, sir, oh, but they were grand
The redcoats couldn't find them, forward or behind them
Cause their eyes were keen, sir, and green the mountain land.

Oh the mountains sing and the valleys ring,
hurrah for those green mountain boys.
