David sings 'Imagine', Rihanna brings 'Rockstar 101', and Kara DioGuardi's protege performs 'In My Head' on the result show.
The April 7 result show of "American Idol" saw live performances from David Archuleta, Rihanna and Jason Derulo. Taking the stage as the first musical guest was Jason. The singer who cited judge Kara DioGuardi as his mentor sang his single "In My Head".
David was the next performer. He sat behind a piano and covered John Lennon's worldwide hit "Imagine". He said he is still a little nervous when performing on the "Idol" stage despite having graduated from the competition. Also, he talked about writing and recording his new album.
The last performer of the Wednesday show, which saw no one going home, was Rihanna. Instead of singing "Te Amo" like it was previously reported, she entertained viewers with "Rockstar 101" which was confirmed to be her next single.
