yeah i hate how people say you had to be there, vertigo at the end rocks, the people go crazy for it!
well fine then, move aboy to the opener, throw in a song like mofo or dirty day or please or last night on earth into the encore and then close with vertigo and wouldnt that rock even more??
vertigo twice is cool when its a random spotaneous thing that the band does when they're feeling it. when its planned its pretty lame. if you like closing with it, thats cool, then do that. just move something else into the opening slot so it makes room for another song.
