No, not the popular U2 song.
Instead, the American Idol crooner fell victim to this dizzying disease during a concert The Tilles Center in Greenvale, NY last week.
Ever the trooper, Clay Aiken went on with the show while holding his balance on a stool and giving a perfect performance for his fans, who rewarded him a standing ovation.
As he was assisted back onstage on the arm of an assistant, Aiken sang the All is Well tune from his Christmas CD for an encore … while both he and fans swooned.
