AceShowbiz - A bitter legal battle has erupted over a potential The Rolling Stones 50th anniversary tour - the band's longtime gig producer has sued bosses at promotions giant Live Nation accusing them of interfering with the plans.

Michael Cohl, who was drafted in to work on the troubled "Spider-Man" Broadway musical last year, was sued by bosses at the massive music firm in November over allegations he breached his contract at the time he left his job at the company in 2008.

He has now launched a counter-suit, alleging Live Nation bosses breached a contract and have been attempting to "interfere" and "destroy" his bid to secure the promotional rights for a tour by the legendary band later this year.

Cohl has produced many of the Stones' tours, and although the group has not announced plans for another trek, it is believed the concerts could kick off in late 2011 to mark the band's 50th anniversary in 2012.

The new lawsuit also reveals members of the Rolling Stones, including Sir Mick Jagger and Keith Richards, have expressed a desire not to get involved in the "spat", while Cohl alleges the dispute is damaging his standing with the band, according to the Hollywood Reporter.
