This Saturday, the likes of Ed Sheeran, One Direction and Chris Martin will head into studio to record the newest take on 'Do They Know It's Christmas?'.
The video for the track will then premiere less than 24 hours later on the X Factor results show on Sunday.
The track - which will also feature Sam Smith, Bastille, Emile Sande and Foals, amongst others - is receiving a re-release to raise funds for the fight against Ebola.
