I'm already looking forward to The X Factor tomorrow night and seeing which contestants really suit the big band theme of the show, and which ones struggle a little with the new musical style. Eoghan, Austin, Alexandra, Laura and Diana were all spotted outside their home base this week, flitting from rehearsals to home with regularity. The final twelve acts have also recorded a cover of Mariah Carey’s "Hero" for charities Help4Heroes and the Poppy Appeal. The contestants will perform it for the first time on the results show this weekend, and the song will then be available to download at midnight shortly after the performance! Will you download it?
