Another one from the great Harlan Howard:

THE WALL
Words and music by Harlan Howard
As recorded by Johnny Cash on "Orange Blossom Special" (1965)

There's a lot o' strange men in cell block ten,
But the strangest of them all
Was a friend of mine who spent his time
Starin' at the wall,
Starin' at the wall.

In his hand was a note that his gal had wrote
And it proves that crime don't pay.
Was the very same gal he robbed and stole for
Namin' her weddin' day,
Namin' her weddin' day.

As he looked at the wall so strong an' tall,
I could hear him softly curse.
"Nobody at all ever climbed that wall
But I'm gonna be the first,
I'm gonna be the first."

Well, the warden came by and said: "Son, don't try.
I'd hate to see you fall,
'Cause there ain't no doubt they'll carry you out
If you ever touch that wall,
If you ever touch that wall."

Well, a year's gone by since he made his try
But I can still recall
How hard he tried and the way he died
But he never made that wall,
He never made that wall.

There's never been a man ever shook this can
But I know a man who tried.
The newspaper called it a jailbreak plan
But I know it was suicide,
I know it was suicide.
