Michael J. Fox Surprises Coldplay Fans with Glastonbury Performance Amid Parkinson's Breakthrough

Michael J. Fox, who has been battling Parkinson's disease since 1991, joined Coldplay on stage at the Glastonbury Festival for a surprise appearance. Fox's appearance came just as his foundation announced a breakthrough in Parkinson's treatment.

Michael J. Fox, the beloved "Back to the Future" star, surprised fans when he joined Coldplay on stage at the Glastonbury Festival in the U.K. The actor, who has been battling Parkinson's disease since 1991, shared photos from the event on Instagram, thanking the band for the experience.

"My team: Lauren, John and Jeff and Steve… Glastonbury all the love and thanks to the @coldplay team who took such great care of us. And many thanks to Chris, Will, Johnny, Guy and Phil," Fox wrote in the caption.

He continued, "Oh yeah in case you were wondering… it was f---ing mind blowing. There is a time for every band and a band for every time. This is @coldplay’s time."

According to Variety, Coldplay lead singer Chris Martin introduced Fox on stage before playing their song "Humankind," saying, "With his Chuck Berry riff and the way he punched Biff: ladies and gentlemen, please welcome Michael J. Fox."

Video shared by BBC Music on YouTube showed Fox stayed on afterward and played along on guitar from his wheelchair during the band’s performance of "Fix You," as Martin knelt beside the actor for portions of the performance.

After the song, Martin thanked the crowd, and added, "Especially thank you to the main reason why we’re in a band, is because of watching ‘Back to the Future,’ so thank you to our hero forever, and one of the most amazing people on earth, Mr. Michael J. Fox. Thank you so much Michael… hero."

Coldplay also shared the video on their official Instagram page, writing, "Thank you Michael J. Fox for making our dream come true."

Fox has previously appeared with Coldplay, joining them during a concert at MetLife Stadium in New Jersey in 2016, where they performed "Johnny B. Goode," the Chuck Berry song featured in "Back to the Future."

The "Spin City" star has been battling Parkinson's disease since he was diagnosed in 1991. In April, the 63-year-old was on Time’s "Most Influential People" list and received a touching tribute from fellow Canadian-born star Ryan Reynolds, thanking him for championing research and supporting others suffering from the disease, including his dad.

"I’ve watched him raise the bar for purpose and passion," Reynolds wrote. "It’d be kinda lazy to simply characterize him as the greatest champion of Parkinson’s research on the planet. He’s someone who helped my dad, along with millions of others, feel less alone. It’d be kinda lazy to simply regard him as a movie star who shaped the lives of people all over the planet with a uniquely electric wit and self-aware charm. He’s the sum of these beautiful parts."

Fox's appearance at Glastonbury came just as his foundation, the Michael J. Fox Foundation for Parkinson's Research, announced a breakthrough in Parkinson's treatment. The foundation announced that it has developed a protein test that can diagnose Parkinson's disease with 90% accuracy.

The test, which is still in the early stages of development, could revolutionize the way Parkinson's disease is diagnosed and treated. Currently, Parkinson's disease is diagnosed based on a patient's symptoms and a physical examination. However, the protein test could provide a more objective and accurate way to diagnose the disease, which could lead to earlier treatment and better outcomes for patients.

The Michael J. Fox Foundation is a non-profit organization that is dedicated to finding a cure for Parkinson's disease. The foundation was founded by Fox in 2000, and it has since raised over $1 billion for Parkinson's research.

Fox's appearance at Glastonbury and the announcement of the protein test breakthrough are both positive signs for the future of Parkinson's disease treatment. The protein test could provide a more accurate way to diagnose Parkinson's disease, which could lead to earlier treatment and better outcomes for patients. And Fox's continued support for Parkinson's research is a reminder that there is still hope for a cure.
