Bernie, Until this year, I played 35 to 40 Christmas parties ever December. I can assure you that more than a dozen songs is far more than they want to hear. And, I'll be more than happy to email you my Christmas Gig Disk, which has a lot of non-traditional styles for traditional Christmas songs - it keeps those parties alive and vibrant. They hired you for the job based on your other performances. It's those songs they really want to hear.
Good luck,
Gary
