Here is a pdf file containing lyrics to 39 Christmas carols formatted as a 10-page booklet. You can print it and/or download it to your tablet or whatever. I carry a copy on my phone so I can rehearse to myself on the bus.
Feel free to sing them for yourselves in your own gatherings. I believe they are all public domain and if not they should be. If you plan to come to D’Arcy’s on December 15, you can use this document to brush up on your favourites in advance.
I hope to see you there, but if you can’t make it, have a Merry Christmas and a Happy New Year, and enjoy singing for yourselves!
