Elton John was the biggest pop star of the '70s, grabbing headlines and generating hits throughout the world. As it turned out, this was merely the first act in a remarkable career that kept him at the top of the charts for over 25 years. He charted a Top 40 hit single every year between 1970 and 1996, a sign that he knew how to both change with the times and mold the times to fit him. Initially marketed as a singer/songwriter, John soon revealed he could craft Beatlesque pop and pound out rockers with equal aplomb. He could dip into soul, disco, and country, as well as classic pop balladry and even progressive rock. His versatility, combined with his effortless melodic skills, dynamic charisma, and flamboyant stage shows, became his calling cards and many of his songs -- including "Your Song," "Rocket Man," "Goodbye Yellow Brick Road," and "Don't Let the Sun Go Down on Me" -- became contemporary pop standards.
