Michael J. Fox Plays Guitar in Back To The Future Songs Onstage with Coldplay

Chris Martin saw his "dream come true" Sunday in New Jersey, when actor Michael J. Fox joined Coldplay onstage!

They covered the Penguins' "Earth Angel" and Chuck Berry's "Johnny B. Goode" – two tracks Fox's classic character Marty McFly performed at the "Under the Sea" dance in Back to the Future (skip to approx. 2.40s to see Fox playing). 

Suffering from Parkinson's Disease, Fox showed us that he doesn't let it get in his way.

"That's our dream come true. Thank you, Michael," Martin said after the performance. "What a wonderful, wonderful, wonderful man."
