Watch: Michael J. Fox Performs with Coldplay at Glastonbury Festival

Coldplay’s set at Glastonbury Festival on Saturday night didn’t disappoint, that’s for certain. The record-breaking performance—as the first act to headline the festival for a fifth time—was filled with incredible songs, fan interactions, and cameos by other great talents. The standout surprise showing, though, came from legendary actor Michael J. Fox, who showed off his guitar skills and played with the band for their songs “Humankind” and “Fix You.”
