“The Rolling Stones — average age 68, if you’re counting — were in rollicking form as they rocked the Barclays Center in Brooklyn for 2½ hours Saturday night, their first U.S. show on a mini-tour marking a mind-boggling 50 years as a rock band.” The Stones will play two shows in Newark, N.J., on Dec. 13 and 15, but before that, they’ll join “a veritable who’s who of British rock royalty and U.S. superstars at the blockbuster 12-12-12 Sandy benefit concert at Madison Square Garden. Also scheduled to perform: Paul McCartney, the Who, Eric Clapton, Bruce Springsteen & The E Street Band, Alicia Keys, Kanye West, Eddie Vedder, Billy Joel, Roger Waters and Chris Martin.”
