Keith Richards at 71: I'm amazed by my 'sheer luck'

Rolling Stones guitarist Keith Richards is releasing his first solo album in 23 years, “Crosseyed Heart,” and is the subject of a new Netflix documentary, “Under the Influence.” He sits down with TODAY’s Matt Lauer, and at the piano (even though he says he’s an “awful” pianist) shows how he composed such songs as “Ruby Tuesday.” He also muses about his mortality at age 71, marveling at the “sheer luck that I’ve had.”
