What do you think about large difference between two shows in Chicago in October 76??? On OS of this tour he sung awful and on this concert he seems not in Stadium! But one day later - he played very very good show! I don?t think that it?s only difference between his mood, but it?s different in his vocal shape too! But why??? What?s happened between 14th and 15th October??? Maybe it?s stupid question, but difference in quality between Chicago Beat and Bringing The House Down is absolutely unbelieavable!
