Aaron Kelly opened last night’s American Idol Frank Sinatra themed show with his rendition of ‘Fly Me To The Moon,’ he was accompanied on piano by this week’s celebrity mentor Harry Connick Jr.

We liked his styling this week. Not so much of the wet head and a more conventional haircut, he looked handsome, and quite a bit older which is no bad thing. Aaron crooned his way through the song effortlessly, and his voice held up well to this genre which is very different to his normal style. He impressed Randy and Ellen but Kara and Simon weren’t so convinced!

Judges Comments:

Randy Jackson: One of the things I was looking for tonight is who’s in it to win this. It’s getting down to the wire. Who’s got the fire? Who’s gonna bring it hard? Sinatra week. I mean, one of the best singers in the world ever. You got the great Harry Connick Jr I can’t tell you dude, I was so worried more about you ‘coz you’re so young. But dude, you did a really good job.

Ellen DeGeneres: I thought the piano was a little pitchy. I was worried also for you and I can’t believe I didn’t hear any country in that at all. I thought you really pulled that off. That was beautiful.

Kara DioGuardi: I thought it was good, I did. Compared to last week though, it wasn’t as strong. And last week you really came into your own. I think you’ll be here again and what I want you to learn is a bit more charisma. Fill up the stage more. Frank Sinatra was just about as tall as you, but he filled everything up, he commanded it. You still need to break out as a performer.

Simon Cowell: I’m more with Kara on this. I adore Frank because Frank was the king of cool. And he had a swagger, he had a believability. And if he was a lion, you were just a mouse. It didn’t have the conviction for me, and I thought the vocals toward the end were a bit corny. And the thing about you – which is a good thing – people like you after your perform. And you do try hard, I’ll give you that.
