Over the weekend, Dave Grohl returned to the stage after giving his broken leg time to heal at a Foo Fighters show in Washington, D.C. still in a cast and sitting on an opulent throne he designed himself while high on hospital meds. The concert was just a part of a celebration commemorating the 20th anniversary of their self-titled debut album, as Grohl also hosted a biker rally earlier that day (July 4), during which he performed with members and former members of Foo Fighters, Pearl Jam and Blind Melon. Check out fan-shot footage of the group covering Neil Young's "Cinnamon Girl" below.

Grohl didn't have his throne, instead opting for a metal folding chair to rest his foot on. The impromptu band consisted of former Pearl Jam drummer Dave Krusen, Foo Fighters touring band member and the Wallflowers keyboardist Rami Jaffee, Blind Melon guitarist Christopher Thorn and Jonny Kaplan, with Grohl joining them for the Neil Young cover and a rendition of the Rolling Stones’ “Miss You.”

It seems nothing can really stop the Foo Fighters train from rolling, as the band, and Grohl's broken leg, will continue on in their North American tour. Find their complete schedule at their website.
