The songs performed included "Think of Me" (sung by David Archuleta), "Memory" (Jason Castro), "One Rock & Roll Too Many" (Syesha Mercado), "Jesus Christ Superstar" (Carly Smithson), "You Must Love Me" (Brooke White) and "The Music of the Night," the Phantom of the Opera anthem, which was sung by David Cook.

Howard McGillin, the Broadway actor who currently plays the title role in Lloyd Webber's Phantom at Broadway's Majestic Theatre, spoke with TV's "Extra" about Cook's rendition of "Music of the Night." Said McGillin, "He nailed it . . . It's such a difficult song to sing . . . He sings with such purity and such a beautiful sound, but he did great." McGillin also told the TV program, "I love ['American Idol' but] I don't get to watch it much."

The April 23 "Idol" results show will feature Lloyd Webber performing live with the contestants. The results show airs at 9 PM ET; check local listings.
