Chris Martin and company were joined by Marty McFly himself Monday night.
At a New Jersey Coldplay concert, Michael J. Fox made a surprise appearance. The Back to the Future star and guitar player backed the band on 'Earth Angel' and 'Johnny B. Goode', effectively reenacting the 1985 film's school dance scene.
Before the numbers, Chris Martin's son appeared on the jumbotron to ask his dad to play a song from sci-fi classic, which he described as his and his dad's favourite movie.
