A rescheduled concert date after Mick Jagger's emergency heart surgery, the Rolling Stones are still alive and kicking! Though memories may be fading a bit, they still know how to start up a concert with "Start Me Up." Jagger said to the crowd on Thursday night, "It’s been 25 years since we played the Rose Bowl! And it’s been 55 years since we first played L.A.!” Uh ...

Fellow aging rockers were in attendance including Billy Idol, with his kids Willem Wolf and Bonnie Blue, Bruce Springsteen, Motley Crue's Nikki Sixx and others. Robert Downey, Jr. opening the gig with this scientific tribute -- announcing the nearby Jet Propulsion Lab had named a rock on Mars after the band: "While landing on the red planet’s surface [the InSight spacecraft] displaced a rock that rolled a fair distance in view of its onboard cameras.” Get it? Rolling Stone. Jagger followed: "I want to bring it back and put it on our mantelpiece."

And so they roll on ... how much longer Jagger, Richards, and gang will be able to deliver as they roll into their late 70s is anyone's guess for for now, the show goes on!
