Sep 28, 1973 - Munich, Germany - Rolling Stones frontman MICK JAGGER pictured during a concert in Munich. Little did the Rolling Stones know how apt their name - inspired by the title of a Muddy Waters song, 'Rollin' Stone' - would turn out to be. Formed in 1962, they are the longest-lived continuously active group in rock and roll history. Throughout four decades of shifting tastes in the arena of popular music, the Stones have kept rolling, adapting to the latest sounds and styles without straying too far from their origins as a blues-loving, guitar-based rock and roll band.
