... steadily for 64+ years. That alone keeps them relevant. To the best of my knowledge, no other band can match that record.
I saw them live back in '69 or '70 in Boston Garden, just a few weeks after the cops had pulled Robert Plant off the stage by his hair at the stroke of midnight. B.B. King opened for them, and after his set, a Stones spokesman took to the stage and proclaimed, "IF THERE'S A COP IN THE HOUSE, THERE WON'T BE A CONCERT!"
A quick confab of cops and promoters resulted in all the cops filing out. My friend, Doug, my wife, Gail, and I were among the first to leave our nosebleed seats to stand in front of the stage. Gail couldn't see anything, so I hoisted her up on my shoulders.
After an instrumental, Mick took the stage. Gail was a huge Stones fan, and when Jagger scanned the crowd in front of the stage, the only face he could see was Gail's. She looked a lot like Jean Harlowe, and Jagger picked her out and serenaded her. Gail was so excited that she peed her pants. I had a wet back for the rest of the night.
I still love those guys. For me, their pinnacle of achievement was the Sticky Fingers album, with the cover designed by Andy Warhol and featuring a real zipper over the high-contrast B&W shot of Jagger's junk in tight Levis. Moonlight Mile still one of my favorite tunes of all time.
