No surprise that Jason Castro was eliminated — and have you ever seen anybody so glad to go? He even sang “I Shot the Sheriff” again so nobody could possibly miss him. I pictured him going backstage afterward, ripping off that frowsy wig and doing the happy dance. This is heading, clearly, for the David vs. David finale that everybody has been predicting ever since David Cook broke out of the pack. Maybe they said this during the elimination show, which I FF’d through to the end (because, seriously: boring), but next week, the final three will each sing three songs –  judges’ pick, producers’ pick and their own pick.
