Huge excitement in the newsroom as we have a Live With Ken Livingstone Special and some of YOU are the stars!
We've got a number of London Tonight viewers coming in to ask questions of the Mayor and all we will be doing is ensuring fare play.
We also want e-mails from you as the programme progresses and we'll read some of them to him too.
So, if it works, it'll be down to you.
Great relief on our part.
We'll also have the news you need with Ben so you won't miss out.
See you at 6.
Alastair and Katie.
