As usual with Joe's Christmas presents, it'll cost you your email (which, if you've gotten his other holiday outings, he's already got anyway) or, possibly, a post on Facebook. Homestly, with Joe, I'm never sure. I just keep hitting buttons until the download starts. Because, when something is as cool and as hot as a free Joe Bonamassa Christmas track, I'll do whatever I have to do to get it.
I'd say you can start your "Christmas Boogie (One Little Kiss)" process here and it'll all work out eventually.
