Many would agree that without Chuck Berry, there would not have been rock 'n' roll. Berry's 1955 debut single, "Maybellene," was an energetic smash hit, and led to a slew of successful late-'50s songs. Influencing such future big names as the Beatles and the Rolling Stones (to name but a few), Berry effectively put boogie and blues into rock. And as demonstrated by his trademark "duck walk," he was also one of rock's original showmen.
