"We presented this performance to the Grammy committee and we just said, 'This is what we'd like to do,' and they said, 'Ok, cool, you have a performance slot.' And then, like a week ago, they call us and they're like, 'Oh, by the way, you're opening the show...' I'm really, really excited about it. I figured they liked what we presented and they wanted to put it first." Taylor Swift on the thrill of opening the 2013 Grammy Awards.
