Im sure i saw a promo just before that it was on tonight. It was a trailer with just the audio of Jonny saying something about kissing.
While on the subject of censoring, having watched the US feeds last year i am not too surprised by C4's tactics. The producer of the the US one continously censored stuff including reward challenges, the nomination process (done round a table) and switched the feeds off during the live eviction show sometimes two hours in advance of the broadcast. Everyone came to hate FOTH which was a shot of the Front Of The House along with the title music which is the equivalent of the birds tweeting and the tube sounds on our BB. It was the whole web thing that made BB what it is. Now the web feeds are seen as a threat to the evening shows.
