At a Green Day concert in Chicago, a fan held up a sign, "I can play every song on Dookie." So Billie Joe Armstrong let him pop on stage to play "When I Come Around." And the fan didn't disappoint, from the moment he climbed on the amp and kicked things off, to his stage dive back into the crowd. The footage was recorded on October 23rd. Enjoy.
