FOR HIS EIGHTH birthday, Mark Alan Stamaty’s parents gave him his very own radio. Little did his mother realize that that innocent-looking plastic box would one day be the gateway for a new kind of sound that would “rock” her nearly out of her mind. . . . Mark first heard the howling thunder of Elvis Presley singing “Hound Dog” on the radio one lazy day and his life was forever changed. Soon he was styling his hair like the King and practicing his dance moves with a tennis racket as his pretend guitar in front o f the mirror. But his mother lived in constant fear that her son’s new love of rock ’n’ roll would turn him into a juvenile delinquent. Could Mark’s performance at his Cub Scout talent show change her mind?
