Performing two songs is a massive bonus, Touch is a amazing single however it doesn't scream album seller, Where Oops sounds more of an album seller.
1D performed two songs on last years final got an 11 minute slot, I think that's exactly what the girls will get this year two full songs they wouldn't fly Charlie over from America just to perform half of oops.
I am excited for the performances, I expect album sales to get a good boost next week, Even know its already still got healthy sales.
