Crystal Bowersox, Alanis Morissette Unite For 'You Oughta Know' On 'American Idol' Finale

Duo perform Morissette's mega-hit after Bowersox's solo performance of 'Ironic.'

Back in February, Crystal Bowersox took the [article id="1640043"]"American Idol"[/article] stage to perform [artist id="996"]Alanis Morissette[/artist]'s "Hand in My Pocket." It didn't go so well. Simon Cowell accused her of sounding like a thousand buskers outside a thousand different subway stations.

Bowersox got her revenge on Wednesday night's (May 26) finale when she united with Morissette for a duet that brought the crowd at the Nokia Theatre to its feet. The "Idol" finalist got the performance started with a solo take on Morissette's "Ironic," a song that reached the #4 spot on the Billboard Hot 100 chart.

She then turned dramatically toward the back of the stage and welcomed her fellow artist onto the stage for a duet of the Grammy-winning best-seller "You Oughta Know," another cut off Morissette's 1995 album Jagged Little Pill. As Morissette strode out under the bright blue lights of the "Idol" stage, the two singers exchanged verses, crisscrossed the stage and finally met in the middle, voices wailing, smiles wide.

Buskers, they weren't. The performance was not without its share of ironies. After Cowell dismissed Crystal's effort in February, the singer bounced back to establish herself as one of the show's undeniable front-runners the very next week when she busted out a killer version of Creedence Clearwater Revival's "Long as I Can See the Light." She hasn't looked back since. And Bowersox has come to count Cowell as one of her biggest supporters.

On Tuesday's show, Cowell praised Bowersox's performance of [article id="1640037"]"Up to the Mountain,"[/article] saying, "I thought that was by far the best performance and the song of the night. And since this is going to be the final critique I'm ever going to give, I would just like to say that was outstanding."
