WHY? GREEN DAY WHY?

WHY? WHY DID THEY PLAY THAT SONG. ITS OLD AND I WOULD HAVE RATHER THEM PLAY WAKE ME UP WHEN SEPTEMBER ENDS. AT FIRST I THOUGHT IT MIGHT BE HALF AND HALF. BUT IT WAS ALL OF THE SONG.!WHY START THE SHOW WITH AN OLD SONG. AND DIDDY'S ENTRANCE IS KINDA OF COOL BUT THE GIRLS AND THEN THE DIVING INTO THE POOL WAS KIND OF GAY. THOUGH I MUST ADMIT DIDDY IS SO COOL! BUT WHAT IS HE DOING NOW?WHY DID HE HAVE TO TALK AND DANCE??OH GOD! NO NOT CHEESY SPECIAL EFFECTS!!ITS KINDA COOL THOUGH AFTER THE CHEESY SPECIAL EFFECTS. I HOPE HE DOESN'T START DANCING AGAIN. THOUGH ITS QUITE UNEXPECTED>?
