Idol star Cook struggling in tour return

AKRON, Ohio, May 10 (UPI) -- Singer Ryan Star says "American Idol" star David Cook is doing his best at their U.S. tour performances in the wake of his brother's death.

Star, who has been touring with the winner of the seventh season of "Idol" since Feb. 14, said Cook has had a difficult time on the road following the death of his brother, Adam, on May 2, People.com reported Saturday.

"It has been a long road for David, and we've seen how tough it has been on him," Star said regarding Adam's passing due to cancer at the age of 37. "I think he's doing the best he can."

The emotional strain on Cook was apparent Friday when the singer suddenly stopped singing a slow song during an Akron, Ohio, performance.

"It's gonna be tough for me," People.com quoted Cook as telling his Musica theater audience Friday night. "Hold on. I'm sorry. Do you mind if I sing a different song?"

People.com said Cook temporarily left the stage during the Akron performance, but returned a short while later to complete his performance.
