Trying to track down this Wild Goose song.

I know most of the lyrics already, more or less:

There’s few who know
Where the wild geese go
So now my love and I
For when cold winds blow
Then the geese must go
Here from my love and I:
They must fly-y
i-iy
They must fly.

If anybody remembers this song and the artist, it’d be awesome. I heard it off of a filk tape, thirty years ago. …God help me.
