I loved the arrangement! It felt like such a '60s variety show performance. Good stuff.

''Come on show em what ur worth''

I'm not giving up on her! lol. Please go back to your old style Katy.

I kinda liked this performance. she looked good and my ears didn't die after I heard her singing

The beginning chorus was a little rough, but by FAR the best performance of Firework so far!

I'm impressed. The arrangement works really well.

I love this version.
And people said that this performance is just pure hater. You can tell that you dont like her voice, but you cant deny that she really can sing.
