Keith Richards looks old, but Jerry Lee Lewis is a generation older. When Jerry Lee was making his seminal Sun Records recordings, Keith was still in short pants (now there’s an old expression). Last man standing (all the other main Sun artists---Elvis, Johnny Cash, Carl Perkins, and Roy Orbison---beat him to the finish line), JLL just got out of rehab.
Jerry Lee and Chuck Berry toured together in one of those "caravan" shows in the late 50’s. Every act got only a few songs, and the one who got the best crowd reaction was given the honor of closing the show. Both Jerry and Chuck, each having a fairly-large ego, figured it should be he who did so. The tour organizer alternated between them, and each tried to outdo the other. On a night Jerry Lee preceded Chuck on stage, during his last song Lewis took out of his pocket a can of lighter fluid and squirted the fluid onto his piano’s keyboard. He then took out his Zippo lighter and lit the keys on fire, playing the rest of the song through the flames. As he and Chuck passed each other at the edge of the stage, Jerry Lee said to Chuck "Follow THAT, n*gg*r."
