Since we all learned that Michael J. Fox was diagnosed with Parkinson's disease, we've all watched in amazement as he continued to work, and work tirelessly. Honestly, he's never missed a beat. Fox has made appearances on a number television series. He even has a recurring role on the CBS legal drama, "The Good Wife." He's really been an inspiration to anyone suffering from a chronic or potentially debilitating illness by refusing let it take control. So it was completely awesome to run across a video of Fox displaying his guitar skills while giving us all a shot of nostalgia. Who can forget the "Johnny B. Goode" scene from the classic blockbuster "Back to the Future?"
