Coldplay fans got a big surprise during Sunday night’s sold-out concert at MetLife Stadium: a surprise appearance by a certain famous New Jersey resident. Bruce Springsteen joined lead singer Chris Marin onstage to perform a couple of his own songs, “Working On A Dream” and “Dancing in the Dark”, with Bruce on acoustic guitar and Martin on piano. Martin is a well-known Springsteen fan and even has the title of “Working On A Dream” tattooed on his arm. Who’s the most famous ‘guest star’ you’ve ever seen at a concert?
