I found it very odd. What exactly would they have been looking at and reacting to in the theatre?

Agree it was very strange. As others have said it’s possible they could see a projection on stage. I assume if it makes it to the lives we’ll find out because they won’t be able to just have nothing on the stage on live TV.

Felt like a bit of an attempt to inject a bit of ‘Masked Singer’ into the show. Interesting idea but not sure it was entirely successful. It will have polarised people for sure, between those curious to work out exactly what it was, those impressed by the (undeniably good) vocals, and those who thought it was a new low, an insult to their intelligence and will proclaim to switch off in protest.
