The Carter Family sang:
The bark of life is tossing down,
The troubled stream of time,
Since first I saw your smiling face,
And youth was in it's prime.
Oh I'll ne'er forget where e'er I roam,
Wherever you may be,
If ever I have had a friend,
You've been that friend to me.
Misfortune nursed me as her child,
And loved me fondly too,
I would have had a broken heart,
Had it not been for you.
I'm very sorry to say I haven't had the pleasure of hearing Sandy & Caroline sing it. That would certainly be a treat.
