In the breaks, we see Dermot and hear something that sounds like 'Giddyaneraa'...what on earth is that?

It's from the song Saturday night by whigfield, hope I've helped in some way.

Yes - thank you!

Do you know what the word is exactly?
To be honest, I find it irritating for some reason

Edit - I just listened to it twice at the beginning of that track, and still haven't a clue what it is! .....suffice to say, I'll be glad when we don't have to hear it anymore!

I've just done a search. Apparently it's Dee Dee na na na not Giddyaneraa.
I'll be honest with you, I also thought it sounded like Giddyaneraa. Again, I hope I've helped in some way.

Dee Dee na na na

Da ba da dan dee dee dee da
Nee na na na - be my baby
Da ba da dan dee dee dee da
Nee na na na - Pretty baby

Thanks to both of you!
It'll still drive me nuts, but at least I know now what it is ...or rather what it's supposed to sound like!

It's really annoying. I think I preferred the judges doing funny faces.

Ahh! not just me then
