WyoWoman,

Your two likeliest sources are The Eagles or Joan Baez.

I found the song on Roughstock.com. There are chords and Tablature (forget you ever heard that word) if you just search for seven bridges road. Here are the words:

Seven Bridges Road

There are stars in the southern sky,
Southward as you go.
There is moonlight and moss in the trees,
Down the seven bridges road.

There are stars in the southern sky.
And if ever you decide you should go.
There is a taste of thyme sweet and honey.
Down the seven bridges road.

Sometimes there's a part of me
(That) wants to turn from here and go.
Running like a child from these warm stars,
Down the seven bridges road.

Enjoy the song. The chord structure seems pretty simple, you might try strumming it.
