Last month, the Waldorf Astoria hosted the benefit A Funny Thing Happened on the Way to Cure Parkinson's. Altogether, $5.5 million was raised for Parkinson's research. And the highlight of the night was the return of host Michael J. Fox to perform Chuck Berry's classic "Johnny B. Goode." And this year, he was joined by Coldplay's Chris Martin, as you can watch in the video below.

Of course, it would have been perfect if they had gotten Chuck Berry—who is still alive—to perform with him. Or if Fox had sung it. Or if anyone had sung it instead of Martin. Although, it's nice that Martin added the "watch me for the changes" line, just like Fox did at Hill Valley High School in 1955.

Fox, who learned to play the song sometime after the first Back To The Future film, also performed the song at the event in 2011, as you can see below.
