Strider,
Thank you so much for sharing your experience of being at this historic run of shows. I was born far too late to have seen the mighty Zep in concert. Your concert breakdowns, in conjunction with the Millard tapes, are possibly the closest a person in the 21st Century can come to really feeling the experience of a Zeppelin concert. To have an in-depth analysis of being at these shows is beyond cool, and to have them in such detail without being completely blurred by drug use. If you haven't already, you should consider writing a book, simply because you write quite well and, as far as I'm aware, there isn't yet a book discussing the 1977 North American tour.
