Music legend Tom Petty gets so nervous before gigs he loses the ability to speak. Despite a career spanning 30 years, the AMERICAN GIRL singer suffers from crippling stagefright. He explains, "I'm really nervous before I play. I don't know what it is, but I get to where I can't even speak a few hours before the show, and once I get out there I'm ok." Petty's convinced his dedication to his work and fans is to blame. He explains, "I don't take it for granted ever. I always want to do my best and give them all I can, so, I really take it seriously."
