Rock legend Chuck Berry still producing music at 80
ST. LOUIS -- As he turned 80 Wednesday, Chuck Berry could leave the hard work of great music to younger souls and rest comfortably as the rock 'n' roll legend who first made his mark in the 1950s. But Berry, the duck--walking, guitar--playing rock genius who defined the music's joy and rebellion in such classics as "Johnny B. Goode," "Sweet Little Sixteen" and "Roll Over Beethoven," has plenty left to say and play.
