Christmas Carols For Bagpipes? ?

OK...so here's the deal...FBC here has already decided to pay me big bucks (they've offered $500 plus a love offering from the congregation) to play at their Christmas party. I'm needing quite a few tunes to make this a worthwhile performance. Anyone have any ideas as to which ones work well and which ones do not? I've never thought about it as I'm not into the whole Christmas thing personally. Thanks!
