This is probably a spoiler, not in the sense as a spoiler for the show itself, but rather for a probably unimportant promotion side thing that currently hasn't officially said by any official sources other than something tucked away on the BBC webside.
   Friday's CBeebies Bedtime Story comes up as "Episode 875: to be advised" on most schedules, however, if you do a bit of digging on the BBC website, you can find this page, confirming a Doctor Who bedtime story airing on the same date. www.bbc.co.uk 

And this raises a lot of questions.
I though it might have something to do with Blue Peter's DW comp, as with the recent authors comp that had a Bedtime Story, they had the same "to be advised" caption, but I did some reading and I don't think it has anything to do with a story. Though they could possibly plug the story on BP.
