I am wondering if tonight's show was recorded last night after the first aired show. Seems crazy to have an audience in, have them all dressed up and just not get on with it. Equally to bring them all back for a second night and dress them up all over again.

Makes sense if the whole thing was recorded last night, and just split into two programmes.

Anyone know which way it was or is being done!

Tonight is live, there were audience tickets available for each show.

Tonight's show is definitely live. Tickets were available for it and Strictly has been tweeting the build up all day!

It's live tonight

Tonight is live, but the Robbie & Gary performance (with Flavia, Ola, Kristina, Katya and Aliona) is pre-recorded, they're doing that about now.
