The 3rd leg was what a handful of dates? That didn't downgrade the tour on its own. From what I understand from those who were there to witness the shows - it was a visual spectacle, especially for back then. The fuck ups weren't as obvious, if you were there. Since we have the luxury, for better or worse, of listening to these shows over and over again - dissecting them along the way - we don't get the whole multi-sensory aspect of the shows. Listening to '77 compared to other years, it doesn't consistently stand up to the high levels of other tours. With that said 6/21/77 is probably my favorite show to listen to, until the fore mentioned solos near the end of the set. Everyone has their own favorites, as far as tours go. I am just glad that we have the variety of shows that we do to enjoy!
Peace.
