I love a good Harrison Bergeron reference. I read that when I was 11 and it's stuck with me ever since. It's so appropriate, so often.

I actually find Lee and Crystal to be very similar. I don't think either of them is as interested in cultivating a performance personality as they are in just singing. The difference is that Crystal already has an inherent personality that is identifiable to a certain extent - the look, the sound, the street folk busker chick, the glimpses into her personality which we've been given through her Coke stool interviews and snippets of judge backtalk - which is what she is. Lee has that midwestern generic guy with the generic hair and generic clothes thing going - which is probably who he is, too. I'm not sure he's devoid of personality as it is that he is devoid of a personality that departs from "plain old dude you'd run into on the train and not think twice about unless he dripped coffee on your shoe." He just doesn't register, where Crystal does.

Casey, on the other hand, has his cheesy "I'm singing now, watch me have fun!" smile and his sway and head shake so his hair settles just-so thing going. As for who Casey is - I have to say I'm not sure. I think he's a guy who likes to play guitar and likes to sing but given a choice of whether he'd want to be Bono or The Edge, he'd go with The Edge.
