While it doesn't appear to have broken rule one in the Official Eurovision Playbook (Don't Forget To Turn Up), or even edicts two and three (Don't Forget The Words, and Don't Fall Over - Even On Purpose), this little performance still manages to obliterate one of the major no-nos in all Eurovisionia. And it is this:
If you're going to insist on having a clever little visual maguffin going on throughout your song, ensure that: A) It doesn't detract or distract from the song itself; B) It's quickly apparent what is going on; C) It doesn't go on too long, and; D) The final pay-off really must be worth the three minute wait.
Oh, and it also helps to have a song that isn't a blood-slowing slice of tedious faux popera, too, but that might just be a taste thing. File under: What were they thinking?
