Charlie Watts provided the foundation that underpinned the music of the Rolling Stones. The band became a by-word for rock 'n' roll excess but for Watts, playing with the Stones did not become the ego trip that drove Mick Jagger and Keith Richards. A jazz aficionado, Watts vied with Bill Wyman for the title of least charismatic member of the band, he eschewed the limelight and rarely gave interviews. And he famously described life with the Stones as five years of playing, 20 years of hanging around.
