First Night of the Proms

Does anyone know why BBC2 are showing 'The Flying Gardener' at the moment when they should be live at the Albert Hall?

I just flicked over as the opening titles were running, so I didnt catch any announcement . . .

EDIT: BBC Radio 3 are playing classical music at the moment, I dont think they are live yet either.

I was wondering what was going on too...didn't hear the announcement into Flying Gardener, had the sound down, so I don't know what is happening.

EDIT: Ten minutes late, but we are there now!

I was listening on Radio 3 just before the programme was scheduled to start and there was a reference a technical problem (with the OB I think) and it was mentioned that would be a slight delay.
