EAST RUTHERFORD, N.J. — Michael J. Fox joined Coldplay on stage at a New Jersey concert where they paid tribute to “Back to the Future” by playing two songs from the iconic 1985 movie.

Fox walked on stage at MetLife Stadium Sunday night just moments after the band showed a video of a fan asking them to play a tune from the “greatest movie of all time.” He then played guitar on classics “Earth Angel” and “Johnny B. Goode.”

Band leader Chris Martin called the moment a “dream come true.” This wasn’t the first time Fox has played with the band. They performed together in 2013 at a New York City benefit show for Parkinson’s research.
