Naah, you're not alone in this. But boy, was I dismayed at how the evening went...I find I'm looking forward to David's performance tonight more than anyone else's. I'm one of the few, I guess, that's pleased about the continuation of the Lennon-McCartney theme.
This was by far my least favorite David Cook performance -- way too much emphasis on performance technique and not enough on connecting to lyrics, though he was one of several who chose lyrics that don't mean much of anything in the first place and don't go anywhere (yes, Michael, Kristy Lee, and Carly, I mean you, you, and you). This one also didn't have enough tune to show off the range he has on that sexy voice. He could have done more with "Day in the Life" than Michael Johns did. Heck, he could have done "Michelle" in a way that would have had the entire front four rows making little squeaking noises of melted ecstasy, and that would have been a little surprise for people who had him boxed as "the rocker."
Also -- way too much clothing! I went back through all of the available video clips (don't feel you have to thank me -- I live only to serve), and IMHO, he's hotter when he seems to have just thrown on a shirt and jeans than when the stylist tries to Blake Lewis him up. He's not Blake. Blake did cool-hip-playful. David does passionate-angsty-hot. This calls for entirely different levels of hair gel.
On the one hand, it's David Cook, who knows how to make every performance into an event complete with fans fainting in the aisles. On the other hand, when he's cuter and sexier in the post-song banter than during the song, this is not a high point for the singing part.
Feel free to tell me at length why I'm wrong, as I'd have to rewatch the video many, many times in order to refute you properly.
