Fox - Fox Rocks Out At Parkinson's Disease Fundraiser

The Back to the Future actor was diagnosed with the degenerative disorder in 1991 and has worked tirelessly to raise awareness about the debilitating condition through his Michael J. Fox Foundation.

The weekend event, entitled A Funny Thing Happened on the Way to Cure Parkinson's, attracted a string of stars including the actor's The Good Wife co-star Julianna Margulies and funnyman Ricky Gervais, who looked on as Fox performed a rendition of Chuck Berry‘s Johnny B. Goode on his guitar. Fox famously performed the rock 'n' roll anthem as Marty MCFly in Back to The Future.
