clipped from: www.greatchristmastime.com Chestnuts roasting on an open fire are all I want when I settle in once more to see the White Christmas film. Downright wrong would be a white (or even a sloppy, slushy) Christmas without viewing the White Christmas film. But don't rely on my word: the 2007 Guinness Book of World Records hails the song White Christmas (from the White Christmas film) the top-selling single of all time, with at least 50 million copies sold.
