Andrew's goodbye song will be his final trainwreck. Yay!
Katie was growing as a singer and growing on me. She probably is one of the four singers who have a versatile voice, the other three being Crystal, Mike and Siobhan. Versatile meaning they can pull off any genre convincingly. Aaron could be versatile, I suspect, because he did do a good job with a little complicated song last night. Casey and Lee can only do one thing.
