The Boston Burglar. Not a transportation song. A cautionary tale about loose-living and its consequences.

You who have your freedom
Pray keep it if you can
And don't go 'round the streets at night
To break the laws of man.
For if you do
You'll surely rue
Behind these bars like me
I am serving the sum
Of twent one years
In the penitentiary.

Note: that's how my Dad taught it to me.
