'Once Upon A Christmas Song', another Gary Barlow co-write, is an affectionate send-up of the festive favourites we sing "over and over and over again" every December. It's catchy enough to get Melvin from accounts shaking his rump at the office Christmas party, silly enough to raise a few titters and there are enough sleigh bells here to make Rudolf think it's time for a trot round the Lapland tundra. The joke hasn't worn thin yet, but Peter Kay should probably pack away his Michelle McManus wig on Boxing Day.
