Last night, all of this year’s X-Factor contestants decided to give something back to the country by releasing a cover version of Mariah Carey’s Hero in aid of Help for Heroes charity.But as the hopefuls took to the stage, two were missing - Ruth and Daniel, both of whom Dannii is mentoring. Was this all part of some nefarious plot by evil king of numbers Simon Cowell? Apparently not - a malfunctioning door has been revealed as the villain of the piece. Though we’re sure the conspiracy theories will continue.Anyway, here’s a look at last night’s amazing performance and don’t forget to head over to iTunes to buy the charity track, or pop into your local record store (if such things still exist) on Monday to pick up a copy.ShareThis
