I may just be a sour englishman, but I find that tactical voting a bit ridiculous. I mean Montenegro vote for Serbia, Serbia for Montenegro, Bosnia are in on it too, as are FYR Macedonia and all the other Balkan states. It happens pretty much every year. Wogan also commented on similar tactics with Cyprus/Greece and Sweden and some other country too.
Though I did like the Serbian song tbh, not bad. Though not sure if the lead singer was a man or woman.
No idea what Ukraine were on...
Edit: And yes, the UK's entry was terrible I digress. Better than last years 'fake/mc/rapper/whatever' entry *shudder* though admittedly not much better. Buxfizz FTW
