Aerosmith drummer Joey Kramer says his decision to sue his bandmates of more than 50 years is "not about money." In a statement released Tuesday, Kramer says his lawsuit has nothing to do with Aerosmith's scheduled performance on the upcoming Grammy Awards telecast, as reported by various media outlets. Kramer, who hasn't performed with the band for the past eight months, says he filed the suit because his bandmates have suddenly turned their backs on him, leaving him out of important milestones he deserves to enjoy. "This is not about money," Kramer writes in his statement. "I am being deprived of the opportunity to be recognized along with my peers, for our collective, lifetime contributions to the music industry. Neither the MusiCares' Person of the Year Award nor the Grammys' Lifetime Achievement honors can ever be repeated. I hope our fans can understand that all I'm trying to do is get back to playing with the band that they love — and that's Aerosmith with all five original members." Do you suspect there's more to the story than Kramer has revealed?
