[Orry Verducci]

I'd be interested to know if Orri knows if those last moments of the channel were live or recorded, and if they were live if the presenters had any idea the channel was about to go off air when they told us to keep watching for the next hour.

It was live. The decision to come off air was made/communicated while that last programme was on air.

The gallery team were informed during the show that live programmes were ceasing after that show, and that was passed on to the presenters, but I don't think they fully realised the channel was coming off air entirely. I think the presenters assumed repeat programmes would be going out (as would normally happen), hence why they said to keep watching.
