Entertainment News: Sophie Ellis-Bextor has recorded the theme tune to Mog's Christmas, a brand new animation coming to Channel 4 this Christmas.

Sophie has teamed up with award-winning composer David Arnold and lyricist Don Black for the track, which is called "As Long As I Belong". It will feature in the brand new television adaptation of Judith Kerr's classic children's book. The ballad illustrates Mog's dream as she falls asleep on top of a snowy rooftop one Christmas Eve.

As well as the theme tune, David Arnold has composed music which fans will be able to hear throughout the 30 minute special, which is likely to air on Christmas day.

Speaking at Air Studios in London where the song was recorded, Sophie Ellis-Bextor said: "When I told my kids I’d been asked to sing Mog’s song, they couldn't really believe it because Mog has been part of our world since my eldest was small, and he's 20 next year! It feels really special."

David Arnold, composer, said: "I'd have been really annoyed if they’d have asked someone else – it takes you back to the days when you were reading the book to your kids, so it's a lovely thing to be asked to do."

Lyricist Don Black said: “We both had such a great time doing The Tiger Who Came To Tea that it was an easy decision to come back for Mog – it's a dream project for a lyricist."

Channel 4 Drama Commissioning Editor Gwawr Lloyd said: “We are delighted to see David and Don collaborate again on a song for a Channel 4 animation, and this time joined by the fabulous and popular Sophie Ellis-Bextor. The song is beautiful and super catchy too! It will transport us all into the wonderful world of Mog for sure.”

Robin Shaw, director said: “It’s such a joy to be working with David and Don again to make a happy, stand-alone song sequence all about belonging, where we’ll see more of Mog and her family in beautifully visualised, Christmassy settings. I’ve included some lovely little actions for children to join in with, hopefully enhancing their own sense of belonging as they watch.”

Other specials set to air on Channel 4 this Christmas include The Great Festive Bake Off and Celebrity Christmas Gogglebox.
