I'm still not in full Christmas mode yet, although I have changed my complete iPod playlist to carols and festive tunes. These range from the trip-off-the-tongue favourites to obscure long-lost ditties. From all of these, it is hard to pick a favourite. However, there is one song that has the ability to total fill my chest with emotion, at any time of the year. And you'll be surprised when I tell you that the first time I heard this, it was the soundtrack to Home Alone.
