BOLOGNA – “With Chuck Berry’s riff andthe way he punched Biff: ladies and gentlemen, please welcome Michael J. Fox”: it is with these words that Chris Martin, frontman of Coldplay, the other evening during the band’s concert at Glastonbury, surprisingly introduced to fans none other than the actor Michael J. Fox, who unexpectedly went on stage for a performance. The Back to the Future actor played two iconic songs with Coldplay, Humankind and Fix You, to the applause of the enthusiastic and moved audience. It happened during the concert on Friday 28 June at the Glastonbury Festival. After the touching performance, Chris Martin once again thrilled the audience by saying: “The main reason why we are a band is Back to the Future. So thank you to Michael, our hero.”
