A girl can dream, can't she?
I think the second encores are a result of a couple of things. 1) The response of the audience and 2) the mood of the guys. Those three hour shows have got to take a ton of energy; I can't imagine getting up there on stage and flawlessly performing their material. I would have been beside myself with excitement if they had given a second encore at the concert I attended. I hope they bring them back, too. It is such a treat.
