 Over the weekend, actor and activist Michael J. Fox took to the stage at a Coldplay concert in Glastonbury in England. Fox was wheeled on stage in a wheelchair but had an electric guitar in his hands. He then joined the band playing along for the band's songs Fix You and Humankind. Coldplay's lead singer Chris Martin said 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, Michael J. Fox.
