(CNN) -- Welcome to the world of rock and roll racing. "He loves the noise, he knows he's a star, he poses for the photographs," trainer Art Sherman --part of the team behind California Chrome, favorite for Saturday's Kentucky Derby -- tells CNN. "Pure and simple he's a rock star." California Chrome's joint owner Steve Coburn is even more effusive. "We've got one elderly gentleman who comes to the races who has a jackass tattoo on his shoulder," explains Coburn, a nod to the jackass on California Chrome's racing silks. "Fans don't do that unless you're a rock star. People flock where he goes."
