Following last year's rapping Yeo Valley farmers, the dairy brand introduces another musical sensation in this spot by BBH. This time it's a boyband, who go by the name of Churned. With the video bearing more than a passing nod to the oeuvre of Take That and Westlife, Forever is heartfelt (and hilarious) ballad to the West Country and organic dairy.

Like the new Muller spot by TBWA/London the spot breaks in tomorrow's UK version of the X-Factor. It will be accompanied by an online karaoke contest, where Facebook users can sing along to the Yeo Valley ad music and will be rated on their performance. The winner of the competition will have the opportunity to feature in a 30 second version of the TV ad, which will appear as part of the live X Factor final on 11th December.

The song will be available to download on iTunes from 6th October and the karaoke competition can be found on the Yeo Valley Facebook page from 8th October. The ad can also be viewed on YouTube (last year's rapping farmers received 1.8 million views there) and on Yeo Valley's website.
