British rock band Coldplay was joined on stage at Glastonbury by actor Michael J. Fox. The 63-year-old, who has been living with Parkinson’s disease since the early 90s, appeared during the band’s performance at Worthy Farm on June 29.

Coldplay’s lead singer, Chris Martin, introduced Fox as a “legend” before the Hollywood star joined them on guitar alongside a large group of backing singers.

Martin expressed his gratitude to Fox, saying, “The main reason why we’re in a band is because of watching Back To The Future, so thank you to our forever hero and one of the most amazing people on Earth, Mr. Michael J. Fox. Thank you so much, Michael.”

Fox later took to Instagram to express his appreciation to Coldplay for the experience, calling it “absolutely mind-blowing.”

During the festival, Martin also paid tribute to festival founder Sir Michael Eavis, singing a heartfelt tribute: “To Michael, we just want to thank you. As humans go you’re the best of all sorts. You’re a musical charmer, you’re the world’s greatest farmer, who ever got knighted wearing shorts.”

Martin praised the Glastonbury audience as the most “peace-loving” and “fun-giving” group, emphasizing their acceptance and non-judgmental spirit.

Reflecting on the performance and the audience, Martin expressed his gratitude, saying, “We’re going to show everybody watching on TV why the Glastonbury audience is the most peace-loving, love-making, fun-giving, accepting, non-judgemental, wonderful group of talented, brilliant humans that can sing in tune.”

He acknowledged and appreciated the diversity of the audience, from those at the front to the back of the field, calling Glastonbury “the greatest city on Earth” and expressing his joy in performing for such an enthusiastic crowd.

Martin concluded by thanking everyone for their support and participation, highlighting the inclusive and celebratory atmosphere that defines Glastonbury for him and the band.
