Crystal Bowersox Performs 'Give Me One Reason' on American Idol

If her straight-outta-the-hospital performance on last week's "American Idol" established Crystal Bowersox as the unlikely front-runner, well, her Tuesday night (March 9) performance definitely put some distance between her and the rest of the field. Miles of it.

Bowersox roared though a version of Tracy Chapman's "Give Me One Reason," armed with an electric guitar and a newfound sense of confidence — perhaps influenced by "Idol" judge Simon Cowell's praise of her during an appearance on Monday night's "The Tonight Show With Jay Leno." She positively blew away the competition, earned a much-deserved standing ovation and absolutely wowed the judges.
