The first hour of 2011 brought plenty of surprises as JAY-Z took the stage. He was joined by Kanye West for an impromptu freestyle performance of Run This Town, Can’t Tell Me Nothing and Runaway. Then as Kanye left the stage, John Mayer joined pal JAY-Z with his guitar for several songs, including Public Service Announcement and 99 Problems.

The show came to a close as JAY-Z, Kanye West and Chris Martin came together for Kanye and Chris’s original collaboration, Homecoming. The crowd then sang along as JAY-Z performed Empire State of Mind and finished his set with Encore. To say the least, “You will never get to see this again,” as JAY-Z summed it up best.
