I don't know, ever since his "I can't wait until Steve Jobs fucking dies of cancer" comment, I really can't bring myself to give any shits. Dookie for nostalgia reasons, that is all.
I think its awesome that Green Day plays so many of these random small club gigs. I think its even cooler they road test their new material, I know they're not the first and only band to do this, but I admire when a group as big as them reward their fans with things like this. Very respectable.
