christmas in december

I know it's early, but I want time to plan and execute this by December. I want to record a CD of me playing Christmas piano music, using my own arrangements and uncopyrighted carols. I don't expect this will go nationwide and sell in big stores or anything, but still, if I'm going to sell this for even one penny apiece, I don't want a copyright hassle on my hands. So that means, no Leroy Anderson... no Sleigh Ride or A Christmas Festival. And good lord, no White Christmas.

I don't have professional audio equipment, but this will mainly be for friends and family anyway and be on sale at church dinners or wherever else I have gigs (and available for order from my website via PayPal). Also, they will just be CD-Rs, as I don't want to go to the cost of producing a minimum 1000 pressed copies.

Anyhoo, I've been compiling a list of Christmas carols that are old enough to be royalty-free, but I'm trying to decide what style these should be. Should I make it a mix? Would it be awkward for one to be in a Jim Brickman style while another is ragtime? If they're all the same style, would it get boring?

Here are examples of uncopyrighted Christmas carols:

Joy to the World
Deck the Halls
The Boar's Head Carol
Here We Come A-Wassailing
What Child Is This
God Rest Ye Merry Gentlemen
Hark the Herald Angels Sing
Good King Wenceslas

I imagine I'll make some of them medleys, e.g. a fanfare of Boar's Head Carol leading into Here We Come A-Wassailing. And I have no idea what carol could possibly be turned into ragtime; it was just an idea. When I play gigs, people sometimes ask if I have a CD, and others have suggested I sell one, but the issue has always been copyrights, so I decided to start with old Christmas carols since they're free.

If nothing else, it'll make my dad ecstatic. :)
