So I presume Strictly is live on the Saturday, the Sunday programme is recorded afterwards on the same evening. If anyone decides to vote ( does anyone, really?) are the lines open till Sunday evening, even though one celeb is voted out live the night before?
It is all done on the Saturday, a few series back they did the result show later on the Saturday which was better as it spoils the results with everyone knowing before the Sunday show, do the BBC think we are imbeciles that we don't know the result show is recorded, all this what happened last night stuff is farcical.
The Beeb has never claimed the Sunday programme is live.
When we are watching the Sunday programme, referring to 'last night's' show is correct, it is indeed the programme we watched last night.
