It’s that time of the year again, when music and dubious taste collide for the Eurovision Song Contest. The line-up of contestants for Saturday’s show was decided at the semi-finals in Athens on Thursday night. More than 20 countries participated, with only 10 slots up for grabs.Eurovision rules mean 14 countries including the UK, France and Germany pass directly to the final, leaving the others to slog it out in the semis. Macedonia and Turkey were among the countries to make it through. Sweden also charmed the voting public, and is now odds-on favourites with UK bookies to win the contest. Making the biggest impression though was Finnish metal band Lordi – also through to the final. Their scary masks, pyrotechnics and hard rock sound have been the talking point of the competition so far – and have raised concerns among some Finns over their national image.
