A woman I worked with used to sing this song, in the 1950s.

Two convicts were seated in a lonely prison cell,
The story of their lifetime to each other they would tell.
When I was a young man, said the elder of the two,
I had a wife, a lovely wife, and a little baby too.

I got home one night after working hard all day,
I found the fireplace empty and my wife had run away.
Twas then I took to drinking, what else could I do?
I mixed with bad companions and became a burglar too.

I set out one night to rob a mansion grand,
My tools were in my pocket, my revolver in my hand
As I climbed in through the window, a gentle voice I heard,
I fired a shot into the room, Oh God, I shot my child.

I remember the tune, I often sing it, but thats all I can remember.
