Harmonica bit

You're mother says I'm a stranger,
my face you'll never see no more.
But there's on promise darlin', 
I'll see you on God's golden shore.

Through this world I'm about to ramble
through ice and snow,  sleet and rain
I'm about to ride that morning railroad
perhaps I'll die on that train

I'm going back to Colorado,
place that I started from.
If I'd know'd how bad you'd treat me,
honey I never would have come.
