New Prisoner's Song
(Dock Boggs)

Sitting alone, sad, all alone,
Sitting in my cell all alone;
A-thinking of those good times gone by me,
Knowing that I once had a home.

For seven long years I've been in prison,
For seven more I have to stay;
Just for knocking a man down in the alley
Taking his gold watch away.

Sitting alone, sad, all alone,
Sitting in my cell all alone;
A-thinking of those good times gone by me,
Knowing that I once had a home.

Oh, once I had a sister and a brother,
Wonder if they ever think of me.
Oh, once I had a father and a mother,
She lived in a cottage near the sea.
Sitting alone, sad, all alone,
Sitting in my cell all alone;
A-thinking of those good times gone by me,
Knowing that I once had a home.
