Michael J. Fox joins Coldplay on stage at Glastonbury Festival 2024

"The main reason why we're in a band is because of watching 'Back to the Future,'" Chris Martin said. "So thank you to our hero forever, one of the most amazing people on earth, Mr. Michael J. Fox." The actor, who's living with Parkinson's disease, played along for two songs -- one of them was "Fix you". During the song’s interlude, Martin sang "Johnny B. Goode" -- the Chuck Berry song featured in "Back to the Future." https://abc7.com/post/michael-fox-joins-coldplay-stage-surprise-performance-glastonbury/15016385/
