I've been collecting my old vinyl on CD and discovered a group called The Halifax Three (the original home of Denny Doherty) (FWIW, RediscoverMusic.com is a VERY bad place for a pocketbook), and they did this song which sounds older and which I cannot find. I suspect there are more verses than they did. It's a sweet song.

It starts off:

I passed by a stream one day as the rain it fell
cool and refreshing and fine as could be.
And there swam a maid so lovely and fair, my boys,
gliding through waters, so pretty was she.
