The key to the Eurovision song contest's appeal is that the music showcased each year bears no resemblance to pop music at all; instead, it's blandified easy-listening rubbish, rather like the work of Celine Dion (who won the contest, for Switzerland, in 1988), but even less challenging, if you can imagine that.

None of the songs ever have any swearing, or political content, or indeed any content at all. The song contest is often used as an immature, childish way of scoring political points - Greece, for example, always votes for Cyprus (which in turn votes for Greece), and not for Turkey.

In Britain the television coverage is narrated by Terry Wogan, who treats the whole thing as a joke, and barely veils a mixture of disgust and perverse fascination at the whole gaudy mess. Imagine the late Carl Sagan commentating on a dog show and you have the essence of Wogan's appeal.
