Votes from this past week's performance show will be combined with votes from next week, giving the four contestants an extra week to impress the judges and the viewers at home.
On the May 2 results show of the singing competition, which also begins at 8 PM ET, the top three finalists will be announced. Season 7 winner David Cook will also perform his new single, “Laying Me Low.”
Former "American Idol" contestants who have taken to Broadway after their stint on "Idol" include Fantasia Barrino (The Color Purple), Clay Aiken (Spamalot), Constantine Maroulis (Rock of Ages), Diana DeGarmo (Hairspray), Frenchie Davis (Rent) and Jordin Sparks (In the Heights) as well as former "Idol" judge Kara DioGuardi (Chicago), among others.
