I would say the stage and screens were incredible and vastly different from the 2007 shows.
Phils voice aside and some lyric mistakes, I'm certain they could have recorded the show and especially the very last one or 3 in London.
Maybe it was a decision due to covid issues, maybe for quality or cost, but definitely odd not to record the last ever shows of such a huge group.
Thankfully there is footage.
I only recorded small clips or certain songs myself but the sound on my videos is exactly how it was in the arena, so I'm very grateful for that.
