Glastonbury Festival is always full of surprises, with secret sets and special guests popping up throughout the five-day event every year. It's become common that headliners will bring out unannounced guests on the Pyramid Stage, and this year Coldplay really took the crowd by surprise.
Michael, 63, who is battling Parkinson's, appeared in his wheelchair. Frontman Chris, 47, credited the actor as the "reason" Coldplay became a band, branding him a "hero" in a sweet tribute. Fans at home were thrilled to see Michael make an appearance at Glastonbury, with many taking to social media to react to the special moment. Some even claimed to be "in tears" as they watched the performance live on TV.
