All through college I sang in a Madrigal choir and, of course, we always did a big Madrigal dinner at the beginning of December each year. Four nights of performances during which a huge roast beef four-course meal was served, medieval dances performed, a fake Boar's Head was carried through the room while we sang the Boar's Head processional and...of course - we sang Wassailing carols while hot Wassail was served.
