OH...the one really popular Springsteen song for Christmas was called Merry Christmas, Baby, but he's done some others like Santa Claus in Coming to Town
Barenaked Ladies and Sarah McLauchlan do a fantastic job of "God Rest Ye Merry Gentlemen" (with a little "We three Kings" mixed in). Definitely very good stuff.
