VIDEO : Dave Grohl Performs With Broken Leg While Sitting on Awesome Throne at 4th of July Concert

Now this is a rock star!
Dave Grohl wasn't going to let a broken leg keep him away from the stage for too long. On Saturday, Independence Day, the 46-year-old Foo Fighters frontman took the stage with his band at their Fourth of July concert at Robert F. Kennedy Memorial Stadium in Washington, D.C., marking the group's first performance since he suffered his injury onstage less than a month ago.
Sporting a purple cast, Grohl sang and rocked out with his electric guitar while sitting on a giant, awesome makeshift throne, decorated with several guitars and stage lights. It's the Iron Throne...of rock!
