There are many songs in which credibility is stretched to the limit. The lad in 'The Farmer's Boy' just happens to knock on the door of the one farmer who will not only take him in, but has a daughter for him to marry and a farm for him to inherit. But maybe it was the last of a long list he'd tried. In 'The Lost Lady Found' she is lost in England, but found in Ireland, because her true love happens to stop for the night at the very house where she has been imprisoned. Co-incidence is strained too in 'The Golden Glove', and 'The Knight and the Shepherd's Daughter', but my current favourite is 'The Golden Vanity', in which a little cabin-boy, whilst bobbing up and down in the water, having swum across from his own ship, manages to drill anything from two to nine holes through what should have been many feet of solid oak, sheathed in copper, and sink the enemy warship, all without anyone realising what was going on.
