At his annual Parkinson's Disease fundraiser in New York, Michael J. Fox recreated the iconic 'Johnny B. Goode' scene from 'Back to the Future.' Hello, McFly!

Fox, who was diagnosed with Parkinson's in 1991, appeared onstage with a Gibson guitar like the one from the 1985 movie and tore through the Chuck Berry classic.

Watch Fox's performance, and check out some photos from the event, below.
