Ooooh, Gerhard is developing sadistic tendencies ... :-)

I hear the train a comin'
It's rollin' 'round the bend,
And I ain't seen the sunshine,
Since, I don't know when,
I'm stuck in Folsom Prison,
And time keeps draggin' on,
But that train keeps a-rollin',
On down to San Antone.

When I was just a baby,
My Mama told me, "Son,
Always be a good boy,
Don't ever play with guns,"
But I shot a man in Reno,
Just to watch him die,
When I hear that whistle blowin',
I hang my head and cry.

I bet there's rich folks eatin',
In a fancy dining car,
They're probably drinkin' coffee,
And smokin' big cigars,
But I know I had it comin',
I know I can't be free,
But those people keep a-movin',
And that's what tortures me.

Well, if they freed me from this prison,
If that railroad train was mine,
I bet I'd move out over a little,
Farther down the line,
Far from Folsom Prison,
That's where I want to stay,
And I'd let that lonesome whistle,
Blow my Blues away.
