"When Ozzy calls and asks you to go on tour, you say, 'When do I start?' Over 25 years ago, Ozzy took Motley Crüe on, what some say, was one of the greatest tours in rock history. When he asked us to co-headline OzzFest with him this year, we were flattered and ecstatic. It is an honour and a privilege to share the stage with him again." Rocker Nikki Sixx can't wait to hit the road with Ozzy Osbourne again this summer (10).
