Let me highlight something for all you very fortunate souls who have never encountered the Eurovision Song Contest....it's a load of tripe

And the funny thing is that practically everyone involved with it thinks its a load of tripe too, and it's one long mickey-take from beginning to end

Terry Wogan, a very popular presenter over here (kind of like David Letterman or Jay Leno, only without the charisma

), hosts it and spends all night gradually getting drunker and drunker, taking the mickey from all the acts, but in a very subtle, dry and Irish way.
People over here hold Eurovision parties, where they all sit and watch the contest, get drunk, and have a good laugh over how seriously everyone who's not British seems to take it. It's also very political - if one country and has done something to annoy another country, their song will get 'nil points' (said in French accent though) and there's a great deal of favouritism too - like, for example, all the Scandanavian countries will vote for each other, all the British countries will vote for each other.
And all the songs are completely and utterly awful. I cite 'Making you Mind Up' by Bucks Fizz (which has been playing all day on the radio over here), 'Ooh, Aah, Just a Little Bit' by Gina G and something awful by Sonia who no-one has heard of since the 1980's when she last had a record out.
It's a very British (and European, to an extent, though they take it far more seriously) thing and I guess you'd have to be European to appreciate how absolutely hysterical the entire thing is. Which is why I'll probably be watching it along with the rest of the country so we can all laugh about it come Monday morning at work
