For all of the references to changes for the tour; these are largely because it's a transfer of the Broadway version in terms of music & lyrics, with the song changes and additions.
The show is remarkably epic for a tour & has amazing staging, cast & effects. The video projection screens aren't automated moving blocks across the stage, but are on all side and move up/down along with other scenes that come down or from the side of the stage. Some of the effects remain & are still incredible. The staging in some ways feels more epic because of so much moving on & off the stage. The lighting is incredible too, as is the sound.
My only disappointment (which is hard to say as it's one of my top shows!) is the lack of the best illusion, which was the appearing/disappearing of Sam in the original. This isn't present & I expect would be too complicated to tour (and control the lighting of each venue!). If anyone hasn't seen that illusion, just watch the Blue Room illusion on YouTube as it is immense.
The good thing about it being a Broadway transfer is that the two weaker songs from the West End version are replaced with the superior songs from Broadway.
I will definitely be seeing this tour several more times and really is the most complex & epic touring show I've seen. It's spectacular, gorgeous, stunning & moving.
Could you posit YouTube link of the blue room illusion please ?
