Have you heard One Direction’s Christmas tune yet?!

This is pretty hilarious. If you wanted to see your favourite boyband in Christmas jumpers, singing a Christmas favourite and playing children's instruments – then you're in the right place!

One Direction appeared on The Tonight Show with Jimmy Fallon and did a great (okay, alright) version of Santa Claus is Coming to Town with The Roots. 

Niall just looks so delighted with his little banana shaker! We love it.
