This song isn't a great live song. It's got a lot of places where it's easy to go off key (including the chorus), and the range required is pretty intense. That being said, I thought she was pretty good, but it's not as good of a song live as Skyscraper.
That was really good and I think she and the backup vocals were the only one that found out about the lyrics thing, so it's not a big deal. I loved it. This song is awesome.
