Last night the actual Idols performed on ‘Idol Gives Back’ (tonight is when the celebrities perform, and Thursday is eliminations–whew!). The theme, as it was last year for the charity show, was “inspirational songs.” Here are my two favorite performances from last night: first, Jason Castro doing a restrained and lovely version of “Somewhere Over the Rainbow,” and accompanying himself on the ukulele; second, David Archuleta playing piano and singing a cover of Robbie Williams’ song “Angels.”Enjoy.
