I believe it's recorded months in advance, so no.
Reading on teletext yesterday, I've been proved wrong.
Guest presenters are going to be brought in. As well as being good news for William Hague/Boris Johnson/all the rest now HIGNFY has finished for this year, it also tends to indicate that Richard's recovery will be protracted. He's not out of the woods yet!
Stephen Fry, Lesley Garratt and Tim Rice are tipped to stand in.
What a strange combination!
