The race to become Christmas number one is well and truly underway, and this year there's brand new competition in the form of Flakefleet Primary School from Lancashire.

Together with their teachers, the students have written, recorded and made a video for their song called 'Light Up'.

Apart from reaching Christmas number one, they're hoping to raise money for the Alzheimer's Society, a charity that helps adults with a brain disease called Alzheimer's.
