Only at a Rolling Stones concert could appearances by Bruce Springsteen and Lady Gaga seem almost like afterthoughts.

 Those superstars and other top acts including the Black Keys and John Mayer jammed with the Stones on Saturday night, winding down a series of concerts celebrating the 50th year of rock's most enduring band (the occasion was also marked by a pay-per-view special). 
  
 The Boss rocked out with the band on out "Tumbling Dice"; Gaga matched Mick Jagger shimmy-for-shimmy on "Gimme Shelter"; the Black Keys joined on "Who Do You Love," and John Mayer and Gary Clark Jr. showed their considerable guitar chops alongside Keith Richards and Ronnie Wood on "Goin' Down." 
  
 But the Stones would not be upstaged. While the sold-out crowd roared with each special guest, it was the aging but dynamic foursome that generated the most excitement of the night, as they put new energy into their decades-old catalog of hits, including "It's Only Rock 'N Roll (But I Like It)," "Start Me Up," "Brown Sugar," "Sympathy for the Devil" and more. 
  
 The band took a moment to acknowledge the shooting deaths of 20 children and six adults at an elementary school Friday in Newtown, Conn. "We just wanted to send our love and condolences to all the people who lost loved ones in the tragedy in Connecticut," Jagger early on in the concert as the audience applauded. Jagger noted the entire world was feeling the pain of the stunned nation. 
  
 But it was the only somber moment in an a frenetic show that showed why the Stones are considered by many to be the greatest rock band, and belied the much-discussed advanced age of the group's lineup (their ages range between 65 and 71). 
  
 Jagger himself poked fun at the senior citizen status of the band and their fans; speaking of the pay-per-view crowd at home, he joked: "Some of you have got your grandchildren watching you." 
  
 But few acts in their so-called prime would have been able to match the energy the Stones radiated onstage. The group had the crowd on its feet for the entire show as Jagger gyrated across the stage, his voice in top form. Both Wood and Richards dazzled on guitar (Richards got a raucous, sustained ovation as he took over vocals on two songs). And Charlie Watts kept the beat strong on the drums. 
  
 Before performing in London together late last month for the first of the concerts, the Stones hadn't performed in concert together since 2007. Going into these shows, there was some speculation that Saturday's concert, held at the Prudential Center, might be their last. 
  
 Earlier in the evening, Jagger teased that the concert might signal the end: "This could be the last time; I don't know," he said. But by the end of the evening, it seemed clear that the question was not when the Stones would return, but when. 
  
 "This is the last show of our anniversary tour, and we hope to see you all again soon," Jagger said. 
  
 Perhaps the night's most special guest was Mick Taylor, the former Stones guitarist who was part of some of their biggest moments from 1969 to 1975, when he left the group. He rejoined his band mates (and the man who replaced him, Wood) onstage for a powerful performance of "Midnight Rambler". 
  
 At the concert's end, while other special guests gave their final bows and left the stage, Jagger motioned for Taylor to stay, and the five took their final bow together.

 http://www.rollingstones.com ||||| Given yesterday's devastating events in Connecticut, it seemed impossible for NBC to put together a Saturday Night Live cold open that could be seen in any way as appropriate for the mood. In the end, they eschewed any attempt at making the audience laugh—instead going with a touching performance from the New York Children's Chorus. |||||
Output:
Saturday Night Live shelved the jokes for last night's Cold Open, opting instead to let the kids do the talking in the wake of Friday's Connecticut school shooting: The show opened with the voices of the New York Children's Chorus singing "Silent Night" without accompaniment, reports Deadspin. After the kids closed out the song, they shouted the obligatory, "Live from New York, it's Saturday night!" But it was far from the only tribute out there last night and this morning: The New York Times ran a simple list of the victims' names as its main front-page art this morning. Here's an image. As the Rolling Stones rocked out with Bruce Springsteen and Lady Gaga on the final show of their 50th anniversary tour, Mick Jagger paid tribute to Newtown's loss, reports the AP: "We just wanted to send our love and condolences to all the people who lost loved ones in the tragedy in Connecticut," he said, adding that the world shared America's shock. Fox is yanking new episodes of Family Guy and American Dad tonight to avoid airing content that might be sensitive in the wake of the shootings, notes Huffington Post. And Pope Benedict XVI touched on the tragedy in this morning's mass in St. Peter's Square, notes Reuters. "I was deeply saddened by Friday's senseless violence in Newtown, Connecticut. I assure the families of the victims, especially those who lost a child, of my closeness in prayer. May the God of consolation touch their hearts and ease their pain."
