Brunno, and others,
I can't imagine why anyone would add "yeah you alright" from one show to another. My recollection is that Mark shouted something (it varied) during the intro of 'Calling Elvis' many times on the tour.
I could assume that as it is not an experience of a particular show in its entirety but rather a compilation of different shows, then the very nature of OTN's proposal leaves room for them to put together the show with the intention of bringing a somewhat "cinematic" product, in the sense that a lot of production was done, so it's likely that those involved in the production had the idea of giving this "face" to the show, creating layers like that greeting in CE's introduction that doesn't match any of the shows in Nimes and Rotterdam that were used for OTN. It is clear to me that the song CE on OTN was built in the studio, they used parts from at least 3 shows and built what we can see and hear in this version on OTN, this does not give the listener a real experience, in a certain sense it is a fiction , does it have artistic value? Certainly, but I would give it a greater historical value if it were a version of a single show, a more honest, less "Hollywood" experience.
You pose interesting questions. The concept of CE as a montage was made possible by the click track, as Mark could pick and choose licks from various nights. But this means that the "OTN version of CE" is not a live performance in the normal sense. And for the video, they must have made sure to edit around this.
Exactly, my dear, I can imagine Mark's selection process by listening to the audio recordings of the shows that were recorded and informing how he wanted the final product to look. Once the audio was defined, with the sections desired, certainly by Mark Knopfler, he probably started the process of editing the video for this song, which is why it is the song in the video that appears most in scenes from different scenarios, starting in Rotterdam, (pedestal with two microphones ) and suddenly scenes of the band appear in Nimes (a pedestal with a microphone), so it must have been a very ingenious job to edit this video, in the end, there are two edits, the audio and the video, then synchronize video and audio and do their best to look like a recording of a real performance, it's no surprise that all the musicians are wearing the same clothes.
