NEW YORK (AFP): Bobby Keys, a defining saxophonist of the rock era who offered a jolt both musically and personally to the Rolling Stones, died Tuesday. He was 70. Keys, a hard-partying jazz lover born in Texas, befriended Buddy Holly as a teenager and gradually became a go-to saxophonist for rock acts including the Rolling Stones - whom he first stumbled upon in 1964. Keys provided the tenor sax that contributed to the blues sound of ‘Brown Sugar,’ one of the Stones’ greatest hits, and toured with the rock legends for most of their five decades as a band.
