Robbie walked out on reunion

It's emerged Robbie Williams walked out on Take That only months after they got back together.

A new documentary film reveals Robbie thought he wasn't up to it, and that he lacked the "energy" for the reunion.

However his bandmates rallied round - with Mark Owen convincing him step by step how he could ease his way back in.

Cameras filmed the group during the making of their comeback album for a new documentary Look Back, Don't Stare: A Film About Progress.
