Back in World War II my father was stationed in New Guinea, and of course Bing Crosby's 'White Christmas' was very popular in those days. My mother told me (my father never spoke of his war experiences, never ever, but he must have told her this) that the Ozzie soldiers would sing "I'm dreaming of a white mistress".....being as how the New Guinea lasses were what used to be called 'dusky'.

It was regarded as being very risqué and naughty, apparently!
