Todd Rundgren turns 64 today. He made his mark with such self-written gems as "Hello It's Me," "We Gotta Get You a Woman," "I Saw the Light" and "Bang on the Drum." Then he enhanced his reputation producing Grand Funk's We're an American Band and Shinin' On albums -- and really hit the jackpot as producer of Meat Loaf's legendary Bat Out of Hell. This summer, the Philadelphia product is in his third stint with Ringo Starr's All Starr Band.
