I love Gareth Malone, and as good as this is that it's for charity, and as gorgeous as it sounds, it's ultimately quite a dull song (meaningful yes, but dull nevertheless), and I'm pretty against the principle that it should go to Christmas #1 just because it's for charity, or as part of an anti-X Factor campaign.
Out of this and Little Mix, I prefer the latter, but I'd much rather a Christmas song took it, or Dominick The Donkey
