A behind-the-scenes documentary of Coldplay's world tour has been put on hold because frontman Chris Martin is too busy to edit the footage. The Clocks rocker commissioned his film-making best pal to shoot over 600 hours of film as he followed the notoriously publicity shy group as they toured their X+Y album. But Martin insists he must be involved in putting the TV documentary together, and is currently to busy to go into the editing room for an extended period of time. An insider tells British newspaper the Daily Star, "The camera has been with them all over the globe capturing some amazing gigs and special moments. "It's brilliant stuff but as there's loads of it, editing won't be simple. Chris is very hands-on with Coldplay and wanted to check everything himself. "The footage that's been viewed so far is cracking, so it's a shame the project might not see the light of day."
