Day 6: 17th Century

Some context for the following song: in England, Christmas was celebrated in a completely different way that would be near unrecognizable to us. Around this time for example, it was the equivalent of taking Mardi Gras and Halloween, throw both of them in the snowy December, add plenty of alcohol, some drunken mobs and that was Christmas in a nutshell. If anything, since the Medieval ages, the poor held up a practice in which they would go to the front door of some wealthy person to basically threaten them that if they don't give them booze and food, they'll basically destroy the place. Of course, this is what carolers were originally like. And what exactly did they sing that would fill whoever they visit with dread?
