Very nicely put Nick and hopefully it should put your mind at rest Detective?
Having been a moderately long-time supporter of the band (and I'm a newbie compared to many here!), I can say that the show does differ from venue to venue and you soon realise why, when you see a lot of shows. It is as Nick says down to many factors that govern the venue and what the promoters and local rules allow and ultimately there is cost to be considered.
Unfortunately without this knowledge or understanding, people go to a show and expect to see the exact same thing that people have described at other shows, that may have been at larger venues, with differing financial arrangements or agreements. They are then confused about why some elements may differ. The inflatables are large and not many venues have room, lasers are often not permitted in some venues.
I for one have never felt the band is 'under attack' and I have been a keen follower for a few years now. I personally am confident they will continue to provide some of the best live acts available, for as long
as they choose to do so.
I reckon the loyal faithful here would agree with that too?
There is to my knowledge no big pink hammer and your fears are totally unfounded. So fear not fellow floydian, the black helicopters are not out to get you just yet
