Michael J Fox has made a surprise appearance at a Coldplay concert to play two songs from Back To The Future.

Fox walked on stage at the MetLife Stadium in New Jersey after the band played a video from frontman Chris Martin's son Moses asking them to play a tune from the "greatest movie of all time".

He then played guitar on the rock'n'roll classics Earth Angel and Johnny B Goode.

Martin called the moment a "dream come true".

Back To The Future's Predictions

It is not the first time Fox has played with the British rockers.


They performed together in 2013 at a New York City benefit show for the Michael J Fox Foundation for Parkinson's Research.

Fox, 55, was diagnosed with the disease in the early 1990s.
