My wife's obsessed with Eurovision, and before we had kids we used to go watch it all over Europe. I couldn't care less, but it was a great excuse to visit places we wouldn't normally go - so places like Kiev, Belgrade and we now live in Helsinki because we liked the place so much after coming the year Finland hosted.
She can tell you everything about all the songs weeks beforehand. I'm a bit disappointed Finland didn't get through to the final as they would have done well in a bigger public vote and it was a good cause, but hey.
So based on the last few weeks of all the songs being played in our kitchen - Estonia are a good shout actually. Australia might do OK as they're inoffensive enough that folk won't avoid voting for them, whereas the rest of Europe always has countries they've pissed off. Russia and Spain will be up there, Romania aswell. Serbia appear to have entered a blue whale.
