A documentary on Bruce Springsteen, Springsteen and I, was just released and includes an interview with 27 year old Nick Ferraro of Conshohocken. Ferraro was interviewed due to his father, also Nick Ferraro, climbing on-stage at a Bruce Springsteen concert in Philadelphia in October of 2009 dressed as Elvis. Dressed as Elvis, Ferraro performed a song with Springsteen. You can see him in the video below starting at the four minute mark.
During the concert, the younger Ferraro was next door at Citizens Bank Park watching the Phillies. He texted his mother and jokingly asked if his dad had got on stage yet with Bruce. When she replied that he was on stage at that moment, the son did something that helped land the story in the documentary (they didn’t tell me what, so you will have go see the movie).
