Broken leg, shrmoken leg: Earlier in the day on July 4, before Dave Grohl took the stage atop an elaborate light-up throne at Foo Fighters' 20th anniversary Fourth of July blowout at RFK Stadium, Grohl stopped by a motorcycle rally in Washington, DC, as Spin points out.

Below, watch video of Grohl covering Neil Young's "Cinnamon Girl" with a band comprising former Pearl Jam drummer Dave Krusen, keyboardist Rami Jaffee, and Blind Melon guitarist Christopher Thorn.
