Aaron Kelly, a 16-year-old high school student from Sonestown, Pa., forgot his lyrics in his last performance, which he describes as his defining moment. I hope for his sake it isn't, since at the top of the show, Simon said they all had a lot of nerves in rehearsal and that if anyone forgets their words, "your career is over." Yikes! He sings Rascal Flatts' "Here Comes Goodbye." He sounds pleasant enough, and he doesn't forget any words, but I'm not jumping up and down or anything. Simon says that bearing in mind that this was his first live show, it was quite a good performance. But, he goes on, he looks almost embarrassed to be there, and he needs to have self-belief and -confidence. Kara says he is her favorite kind of contestant because he has no idea how good his raw talent is, so he will grow more and more each week. Randy says he has a huge voice, and though he was worried at first, Aaron pulled it off. Ellen says, "Ditto to all that." She goes on, but she doesn't add much beyond that.
