Here's what spokeswoman at the hospital said last week:
"We're asking for everyone’s support in helping this single make the number one spot this weekend. Sony are donating all profits from the sale of the single and a number of retailers are also very kindly donating all their profits from the sale of the single.
"Please ask everyone you know to buy/download this single now – it doesn’t cost much but every single bought will make an incredible difference to the sickest children in the UK right now."I love X Factor of course, but I love part-time dinner lady, full-time diva Geraldine more - hence the video. And anyway, the genius behind Geraldine will be topping the charts pretty soon for sure so please do still also back the X Factor's effort if you can!
