This is the Delmores version which I said was a different song. Still the structure of the song is similar. There's a great version of IIIrd Tyme Out playing this on YouTube.

BROKEN HEARTED LOVER - Delmore Brothers

How could I be feeling happy
When you don't love me anymore
You took my love and all my kisses
And you left my heart so sore

I'd rather swim across the ocean
Without the help of God or man
Than be a broken hearted lover
When I have done the best I can

I thought that you were an angel
When I first looked into your eyes
But now I know all about you
I know your home's not in the skies

Stop, look and listen for that whistle
And when you hear that lonesome sound
You'll know by the whistle of that freight train
Your broken hearted lover's gone
