Last night’s 50th anniversary gig at the Prudential Center in Newark saw The Rolling Stones still very much at the top of their game, as the band performed some of their greatest hits and collaborated with a star-studded list of guest performers.

Among those were acts like John Mayer (bet you didn’t see that one coming), who rocked out alongside Keith Richards, giving the rock legend a run for his money, as well as The Black Keys and none other than the Boss himself, Bruce Springsteen, who joined The Stones for Tumbling Down. All in all, it was a good night for rock, with the band putting all of their energy into classic hits like 'Brown Sugar', 'Start Me Up,' 'Sympathy for the Devil' and the ever popular '(I Can’t Get No) Satisfaction.'  The most unusual collaboration of the night had to have been with Lady GaGa though, who joined the band for a rendition of 'Gimme Shelter' and it was actually, well, good. The Stones have a history of performing with more poppy artists on occasion, such as Mary J Blige and Florence Welch (of Florence and the Machine fame) and it always seemes to work out. It did again this time, with Gaga flaunting not only her impressive singing chops but also her no less spectacular shimmying skills alongside Mick Jagger.

Last night’s gig also had a more serious aspect to it, however, as the Stones and their guest stars took the time to honour the victims of the recent school shooting in Newtown, Connecticut. “I just wanted to take a minute and send our love and condolences to those who lost their loved ones yesterday,” Jagger commented solemnly, before going into a performance of 'Wild Horses,' dedicated to the victims.

Later on in the evening, the frontman’s cryptic farewell sparked a lot of speculation, as he simply said: “This is our last show... of the 50th anniversary tour. Hope to see you again soon.” Could the band have an extended reunion in mind? One can only hope.
