There is a related song from the Appalachians called 'Pal Of Mine', which Joan Baez recorded many years ago. I learnt it at my mothers steriogramme about 35 years ago, and the record wasn't new then! I later also pinched Peta Webb's verion of Go And Leave Me, which is by far the best I have heard. The Appalachian version is;

Many a night as you lay sleeping
Dreaming of your amber skies (?)
Lies a poor boy, broken hearted
listening to the wind that sighs

My little darlin', oh how I love you,
I love you none can tell,
In your heart you love another,
Little darlin', pal of mine.

Many a day with you I rambled,
Happy hours with you I've spent,
Thought I had your heart forever
But now I find 'twas only lent.

My little darlin', oh how I love you,
I love you none can tell,
In your heart you love another,
Little darlin', pal of mine.

Now there are just three things I wish for,
That's my casket, shroud and grave,
When I'm gone, don't weep for me,
Just kiss those lips that you betrayed.

My little darlin', oh how I love you,
I love you none can tell,
In your heart you love another,
Little darlin', pal of mine.

This doesn't have the dignity of the other does it? But then again, it is being sung from the man's point of view.....

The original Joan Baez recording has been released on cd by Vanguard (VMD2097). It doesn't say when it was first recorded, but the rather sparse notes do say that Joan was 20 at the time, so work it out from there!
