In 2007, sales of Dairy Milk increased by 9% and there was a 20% rise in Cadbury brand approval.  All because a gorilla – that is, actor Garon Michael in a yak-hair gorilla suit with an animatronic face – played the drum fill in a Phil Collins’ classic.  90 seconds of 80s music made Cadbury a fortune; likewise with Bond-style Milk Tray adverts, a lady eating a Flake, the Milky Bar kid, and a boy and a girl with dancing eyebrows.  As a full boarder, I am eligible for a chocolate bar on Wednesdays.  I happen to pick a Cadbury product.
