The Foo Fighters performed a surprise 20-song set at the 9:30 Club in honor of Washington D.C. Go-Go legend Big Tony on Monday night, May 5. The best part: While performing the song "Monkey Wrench," Dave Grohl made his way through the crowd, jumped on the bar, threw back a shot of Jager and then proceeded to unleash a wicked guitar solo for about two minutes. You are champion of the world, Dave Grohl.
