Veteran rockers Bon Jovi are set to release their first band documentary - after decades of watching their rock 'n' roll peers' adventures on film. The Livin' On A Prayer hitmakers have appointed acclaimed filmmaker Barbara Kopple to direct the project as they embark on their upcoming world tour. Guitarist Richie Sambora says, "We just realised that (over) all the years, we really didn't document enough stuff. "We put out a box set a few years ago, but we look at other bands, contemporaries like U2, even Tom Petty and Aerosmith, and they had cameras rolling all the time. We didn't have a lot of footage like that going on."
