kate, they won't hear until January!
There was no-one famous there at all! LOL There was one producer and one camera man in the room where they had to do their audition. No recording of it allowed at all. In fact, mobile phones were supposed to be banned even in the holding room where we were waiting, but no-one took a blind bit of notice!
Sammy got all upset as she messed up in the song a couple of times, but she said the producer was friendly enough.
It was funny to see how they did all their recording of the crowds. After 2 hours of waiting lined up in the street, they decided they wanted to film us all walk through the barriers smiley and happy, so the whole queue of about 400 people had to turn round and 'reverse' up the street so we could all walk back down it with the cameras rolling! 
Then, they stopped us all again before letting us through the barriers to ensure we were smiley and happy enough! 
Once inside, the select few in the holding room were chosen to 'do their thing' on the warm up/practice stage area (Which Jess loved!) while they filmed.
Here's Jess on that area!
And a few other pics.
Don't know if that video will work.
