He told me they forgot to feed them *again* since early that morning. He blames low blood sugar on what he called a sub-par performance; shaking, etc... They cut about a minute of him working the crowd after his song - just as Randy Jackson looked down and started talking, Charlie turned his back and got the crowd engaged again to which the judge replied to his back "ok, soak it in...". Good grief, he told me that after tonight he doesn't care what the judges think since it's up for public votes from this point forward. He's on a mission, like Bilbo or something... What a fun man he has become, and he emulates Freddie Mercury's showmanship, as you can easily see.
