Since Barclays Center opened, and even before, people had been talking about a Rolling Stones concert there as part of the group's 50th anniversary mini-tour. When two shows in Newark were announced, most observers believed that the group's management had chosen that nearby city instead of Brooklyn. However, we've received official news that the "World's Greatest Rock and Roll Band" has added a show at Barclays on Saturday, Dec. 8. Whether this was the result of last-minute negotiations or it was part of the plan from the beginning, nobody's saying. But we do know that tickets are going on sale on Monday, Nov. 19 at 10 a.m. Visit barclayscenter.com.
