For those of you who don't know (and why should you?), a "Ceilidh"--pronounced "kay-lee"--is a Scottish dance party, usually featuring great music, food & alcoholic beverages, and traditional Scottish folk dances. This is not performance dance, but participatory dance, like a barn dance or square dance, where everyone can join in--and if they don't volunteer, they are often pressed into service.
My friend Bethany's husband Patrick is a graduate of the University of Glasgow, where he earned his MLitt in Philosophy, and the University was throwing an alumni dinner at the Harvard Hall of the Harvard Club in Manhattan. We went and gawked at the decor and enjoyed the food and wine, got in a few dances, sang "Auld Lang Syne" (obligatory at every ceilidh I've been to) and managed to stumble home not much later than midnight!
