Fairytale of New York (Shane McGowan) is my bestest favourite (right now anyway). But all christmas songs are fun because most people sort of know them & its a good excuse for a howl-along. Someone sang a really great trad one on Saturday night, but I can't remember anything else other than I REALLY liked it, & meant to look up the words. It'll come back to me in the middle of the night no doubt.
