I saw Green Day this past Saturday, and saw them last year as well. Both times they played for 3 hours, they played an insanely good mix of songs from all eight of their studio albums, and rocked everyone's faces off. Their setlist was 34 full songs + several mini-covers and acoustic bits. See Jon, it is possible! Green Day is one of the few bands of the last decade or two that will continue to thrive for at least another decade.

Just throwing my two cents in on that.
