Chicago blues legend Muddy Waters' birthday is Saturday, and in his memory his eldest son is putting on a concert in Chicago. Waters died more than 40 years ago, but this weekend's concert will be as close as you can get to seeing him live because it features his first-born son Mud Morganfield. "I was born into the blues," he aid. With a father like his, Morganfield said a career in music was inevitable. His love of blues started in childhood. "I got scolded for beating on furniture," he recalled.
