Barlow expresses concern for Williams

Gary Barlow has revealed his concern for Robbie Williams, and hopes his music career does not send him into a spiral of depression.

Williams is suffering in his professional life currently, with latest single 'Rudebox' slammed by most critics. He has also cancelled parts of his 'Close Encounters' tour, blaming exhaustion.

Barlow, who was close to a nervous breakdown after the failure of his solo career, says he would not wish the same fate on his former bandmate.

"Robbie has hurt me more than anyone else has. But as an adult and a father I'd hate to see him go through what I've been through, because I don't know if he'd come out the other end," he said in his autobiography 'My Take'.

"On a musical level, I know how much it keeps him together, doing this and being successful."
