Michael J. Fox shared the stage with Coldplay at the Glastonbury Music Festival in England on Saturday.

During the band's headlining set, the 63-year-old retired actor joined Chris Martin and the rest of the band members, Will Champion, Jonny Buckland, Guy Berryman and Phil Harvey. As seen in the video, the "Back to the Future" star was on stage sitting in his wheelchair with a guitar on his lap as the band performed "Fix You."

Almost two minutes into the performance, Chris headed over to Michael and continued singing beside him while kneeling so they could be at the same eye level. After that, the band's frontman directed the spotlight to Fox as he performed Chuck Berry's "Johnny B. Goode" in "Back to the Future."

"Go, Johnny, go, go, go," Martin cheered as he performed the iconic sci-fi song on his guitar.

Even in his wheelchair, Michael rocked the stage and even threw out a kick the same way he did in the 1985 film.

"The main reason we're in a band is because of watching 'Back to the Future.' Thank you to our hero forever and one of the most amazing people on Earth, Mr. Michael J. Fox," Martin said, honoring the icon.

"Thank you so much, Michael, our hero."

This was not the first time the "Teen Wolf" star performed "Johnny B. Goode" on the same stage as Coldplay. In July 2016, he also joined the band at the MetLife Stadium as they promoted their new album, "Moon Music," at the time.

Back then, Michael could still stand on his feet and was not yet in a wheelchair.

The Hollywood icon was diagnosed with Parkinson's disease way back in 1991. He was just 29 years old at the time.

Per The Michael J. Fox Foundation for Parkinson's Research, he developed a tremor in his pinky finger while filming "Doc Hollywood" in 1991. This led to a consultation with a neurologist where he later discovered that he had a young-onset PD.

Back then, the actor kept his condition under wraps until the third season of "Spin City." He realized he could no longer hide his illness, so he revealed it to the general public. After another season of the sitcom, he retired from full-time acting and focused on advocating and fundraising for PD instead.

Parkinson's disease is "a progressive disorder that affects the nervous system and the parts of the body controlled by the nerves," according to the Mayo Clinic.

Its symptoms include tremors, slowed movement, rigid muscles, impaired posture and balance, decreased ability to perform unconscious movements, changes in speech and difficulty in writing.
