There is a vinyl record out there by Fay McKay (A-Live at the Dunes) with the Twelve Daze of Christmas on it. As to whether or not you can buy it, I have no idea. I do know that some people have managed to get it out there on youtube and some digital mp3s out there on the net as well. You will most likely find it by searching for The Drunken 12 Days of Christmas (and for some reason they have it as being Bob Rivers - which you can obviously tell by listening that it is a woman).
