I was just wondering if we will be getting a sneak preview of tomorrow's episode during Children In Need? If not, then will anything to do with DW be happening? Peter Capaldi being in the studio for instance?

I heard from a friend of mine earlier in the week, that apparently we will be getting a sneak preview of Sleep No More tonight. A 2-3 minute clip shown during the live telethon.

Maybe we will get a sneak preview of the Christmas episode. Like in previous years?

We only got a preview of Xmas last year was because the series has ended by this time.
Since we still have 4 episodes left, I would say we won't

maybe, but I doubt it.

Nothing in Children in Need as far as I could see unless I missed it. Is this the first time ?
