Ok, a totally random thought that I can't get out of my head, so I'll share it.....the Fading Lights "BAM" segue into Cinema Show certainly split opinion on this tour (mainly as it was something different and unexpected which isn't a bad thing; and it certainly jolted everyone awake!); and the DWTMK/Carpet Crawlers was a previously-tried version.....well, what if the Fading Lights section they did segued into Carpet Crawlers? Would that have worked?
It would certainly have put two really poignant songs together as one 'piece'.
(For what it's worth, I'd always found Carpet Crawlers a bit of a weird encore / closer...up until the last shows where it really worked well. A really poignant way to end the last shows).
For me the medleys work best when there's contrast in moods between the sections. I actually thought the idea of Fading Lights into Cinema Show was a good one, its just that the join was a bit clunky. They probably should of done a small part of the Fading Lights instrumental before transitioning into Cinema Show.
