Is it really that time of year already? Tonight I’ll take my seat with about 200 million viewers worldwide and watch the Eurovision Song Contest, taking place in Lisbon, Portugal. The £18 million show will see 26 countries go head-to-head with a diverse set of songs, and the vote will split between the public phone vote and their regional juries of pop-music experts. It’s three and a half hours of joyful silliness, amazing sets, outlandish costumes and dark mutterings about politics and the future of Europe. It’s a like a lavish wedding with all your strange and estranged relatives turning up in their most fabulous clothes, ready to get drunk, have a dance and air all those techy grievances. This powder keg is going to explode into a massive argument. There’s nothing you can do about it, so just enjoy the party.
