Contrary to tabloid stories, Michael J. Fox is doing well...well enough to play his guitar with Coldplay. It's a pretty well-known fact that Marty McFly didn't sing in the "Enchantment Under The Sea" dance scene in Back To The Future. But, he played the guitar. And he recreated it at Met Life Stadium on Sunday night during their final Head Full Of Dreams tour stop in New Jersey. https://www.facebook.com/coldplay/photos/a.10150274960980253.534856.15253175252/10157226643855253/?type=3&theater
