It's the classiest night in The X Factor calendar, as the acts take on massive hits from the likes of Frank Sininatra and Michael Bublé. That's right, this week's theme is BIG BAND WEEK, and after yet another shock elimination last week, the acts really need to up their game in order to survive. Plus, Sunday's results show will feature the premiere of the brand new Band Aid 30 track and music video.
Question of the Day: What's your favourite X Factor theme?
