WASHINGTON — Marty McFly is back on the scene, and he was right. The kids did love it.

Parkinson’s disease awareness advocate Michael J. Fox, 50, took to the stage of his annual fundraiser Sunday with a familiar looking six-string. The actor, who himself suffers from Parkinson’s, then started accompanying a familiar tune on lead guitar.

Fox’s performance of “Johnny B. Goode” was not only impressive in the face of the disease that targets the nervous system, but it’s also not one he’s used to playing on-screen. The actor mimed the “Back to the Future” scene in the iconic 1985 Robert Zemeckis blockbuster, which the screenwriters set up as the original motivation for Chuck Berry’s record.

Check out the footage from the fundraiser, with a particularly stirring solo just after the 1:00 mark:

Michael J. Fox revealed he had Parkinson’s disease on Nov. 25, 1998. He was first diagnosed in 1991. This year’s annual fundraiser — “A Funny Thing Happened on the Way to Cure Parkinson’s” — was put on by the Michael J. Fox Foundation and held at New York’s Waldorf-Astoria.
