Getting a fan to be part of a performance is nothing new. Green Day did it on almost every show on their last tour. Metallica has been known to haul someone onstage. And most famously, a guy named Scot Halpin subbed in for a passed out Keith Moon at a show in San Francisco on November 20, 1973.
Still, it’s cool when it happens. Someone gets to be a hero–if just for one day.
