Thank God it's been rejected! There's a good (YouTube?) report on the Las Vegas sphere: whoever does concerts or events for it, has to carefully design a performance which will be tailored specifically for that venue and nothing else. Who is going to be able to do that? Very few bands and musicians would be able to, or willing. Maybe they could get some Las Vegas style entertainment set up that keeps running for a long time, but in London? Nah.
Good decision by the mayor.

Plus: ticket prices would have to be really steep to make back construction and running costs. With the way prices for everything are skyrocketing (have you seen how much basic food costs these days?), who could afford them? It would become a white elephant very quickly.
On top of the light pollution...

@Mex Woohoo! I must say that I'm fascinated by the names. I still have only the haziests of ideas of exactly which is which (though Suffragette is the one we all thought of as the Goblin, I think?), I get mixed up between Weaver and Windrush... But overall I like that the different parts now have names. And that they'll update signage as and when and won't spend a fortune on doing all that in one go.
