NEW YORK (AP) -- "American Idol" is boogeying toward another elimination.

Tuesday night's worrisome theme is "disco," and a number of finalists have impressed judges with groovy versions of '70s classics.

As expected, the seemingly unstoppable force known as Adam Lambert had Simon Cowell and the gang wrapped around his finger. The 27-year-old "Idol" frontrunner wowed the panel with his restrained, emotional delivery of "If I Can't Have You."

Paula Abdul — who had a dreamy look on her face — said she felt Lambert's "pain." The judge called the theater actor fascinating, brilliant and a shoo-in for the finals of the Fox singing contest.

In another bold declaration, she also told Danny Gokey he'd make it to the final stretch.
