DESCRIPTION:
The "Coulter" in this song was Robert Coltart (Coulter) who sold his "candy" (sweeties in Scottish parlance) round the houses. His song would alert the children to beg for pennies from their parents to buy his wares (a bit like the music played by ice-cream vans going round the streets). There is no "translation" for the first line as it is just a meaningless set of words for a song meant for children.
