Remember this ???
I really hope you have all seen this video before:
It was a great ad for Carlton Draught, created by Grey Advertising (I think). Its successor, Flash Beer has now been created and is equally entertaining - the Viral Meister blog explains it well, "with a fat man called Kevin Kavendish applying for his dream job of becoming a brewer. After failing the job interview, he strips into a leotard and performs the ultimate parody from the movie Flashdance complete with the score What a Feeling."
I have to agree with the Viral Meister when he says that it might not sell more beer but what it will do is get people talking about the brand.
