SCREW-GUN MULES

As me and my companions were scrambling up a hill, The path was lost in rolling stones, but we went forward still; For we can wriggle and climb, my lads, and turn up everywhere, Oh, it's our delight on a mountain height, with a leg or two to spare!

Good luck to every sergeant, then, that lets us pick our road; Bad luck to all the driver-men that cannot pack a load: For we can wriggle and climb, my lads, and turn up everywhere, Oh, it's our delight on a mountain height, with a leg or two to spare!
