There's an old tune called "The Prisoner's Song" that could be sung to a marching cadence. I didn't check to see if it's in the DT, but it starts:

If I had the wings of an angel
Over these prison walls I would fly
And I'd fly to the arms of my poor darlin'
And there I'd be willing to die.

There are other verses, but that's all I can remember off the top of my head.

I'll check the DT and see if it's there.

cheers, ddw
