I guess you are looking for the lyrics to 'John Brown's March' by Jed Marum, which is a superb song. My husband does it at the folk club, just plays claw hammer on the banjo as accompaniment, first song he has sung solely with a banjo backing but it sounds awesome. Jed has done so many wonderful songs - look up his web site: http://www.jedmarum.com/

John Brown's March (words as sent to me by Jed Marum)

At Charlestown now and on this December morn
The gatherin' crowd neither weep nor mourn
A rousing cheer among the fanfare born
As you come to the end of the line

The snares drums rollin' while the piper plays
It's time to pay for your murderous ways
Your treachorous trading in your traitorous days
You've come to the end of the line                        

                Ol' John Brown, the sun is pourin' down
                You're gonna see the hangman marchin' through the town
                Feet in the air and the world is spinnin' round
                When you dance on the end of the line   

The Shenandoah round your gallows flow
Gentle winds on Virginia blow
Your lifeless body swinging to and fro
Now you've come to the end of the line

Three cheers for justice and the Lord be praised
With John Brown mouldering' in his grave
The free, the honest and the righteous saved
He's come to the end of the line
