John Lewis has unveiled its keenly anticipated Christmas Ad for 2017 with Moz the Monster, a two-minute video set to a cover of Beatle's track Golden Slumbers by Elbow, and it tells the story of a young boy unable to fall asleep due to the snoring and farting 7ft imaginary monster under his bed.

The pair quickly become friends and stay up causing mischief together. However, after a number of sleepless nights, Joe keeps falling asleep during the day. So Moz decides to give him a night light, which when illuminated makes the monster vanish meaning Joe can sleep undisturbed.

But as the advert comes to an end with the tagline “For gifts that brighten up their world,” viewers soon realise when Joe turns off the night light, Moz returns - meaning they can remain friends. 

John Lewis’s Customer Director Craig Inglis said: “This year’s Christmas campaign brings to life the power of children’s imaginations and the joy of great friendships. Moz and Joe’s story is magical and heartwarming and I’m sure it will be loved by all of our customers, young and old.”
