Katy Perry - Firework live @ AMAs 2010

Using a children's choir, pop megastar Katy Perry delivered another performance of Firework. But because of the children's choir, the first half of the song was turned into a ballad, which isn't something Perry's spectacular at. They outsung her and stayed on pitch more than she did. Nevertheless, the sparklers came out and Firework hit it's full swing when the adrenaline pumping chorus rang through the room. Kidding. It wasn't that great. It's the usual Katy Perry performance. Just with a children's choir. But hey, at least she tried to do something different.
