Richards' tribute to Gram

Rolling Stones guitarist Keith Richards headlined two Los Angeles tribute concerts to Gram Parsons, the late country rock pioneer.

Norah Jones, Steve Earle and Lucinda Williams were also among the acts at Return to Sin City: A Tribute To Gram Parsons.

Parsons, who died in 1973, was said to be too much of a hellraiser even for the Rolling Stones.
