The ageing rocker has enjoyed a colourful life featuring six marriages - one to Cher

The makers of the upcoming CBGB movie are now working on a Greg Allman biopic.

Writer-director Randall Miller and screenwriter Jody Savin have acquired the rights to My Cross To Bear, the musician’s best-selling memoir, which was published last May (2012). Allman and his manager Michael Lehman will serve as executive producers on the film adaptation.

Allman, now 64, is best known for fronting The Allman Brothers Band, a massive live draw in the ’70s who scored hits with blues tunes like ‘Ramblin’ Man’ and ‘Jessica’, now the theme to BBC’s Top Gear. Allman’s personal life over the years has been colourful, marked by several stints in rehab and six marriages – one to Cher.

The biopic will focus on Allman’s ’70s heyday as well as his recent efforts to clean up his lifestyle. Director Randall Miller told The Hollywood Reporter: “We knew it was a great story but didn’t know how great it was until we read the book. That journey and coming out the other side is not the normal falling-into-hell story that rock ‘n’ roll often is.”

The film will feature a mix of original songs and Allman covers performed by the cast, though the makers have yet to start searching for their lead actor. Meanwhile, Miller and Savin’s eagerly-anticipated CBGB movie is currently in post-production. It stars Alan Rickman as the club’s founder Hilly Kristal and features Foo Fighters drummer Taylor Hawkins as Iggy Pop – click here to see the first picture of Hawkins in character.
