That should be Old Nick at the start there Joe.
I can't remember the words, but the gist of the story is, the devil was going to Marlborough when he met a man (Shoe maker? ), and asked directions. The man had a sack of old shoes, and rather than tell the devil the road to go, he empties out the sack, and says, I can't tell you how far it is, but I wore out all these shoes, since leaving Marlborough. The devil says, if it's that far, I won't bother, and goes back down to hell. The pile of shoes was left there, to gather other bits of detritus over the years, and to eventually become Silbury Hill.
