Rocker Steven Tyler has the answer to his SIR Mick Jagger and Iggy Pop's long successful careers - their attitudes. The Aerosmith singer insists he and his contemporaries are far from the most talented performers of their generation, but have stuck around because of their personalities. He says, "(Pop) doesn't have the greatest voice, but neither do I and neither does Mick. "But what we've all got is the attitude. Iggy just does not stop."
