Eurovision fans arrive in Basel for the competition's first semi-final, with supporters travelling from around the continent to cheer on their favourite entries. "We are very proud," says Sabrina Dittli, a fan from host nation Switzerland. Another of those waiting outside the venue is Petra Manival, who has come from Germany but in support of Estonia's Tommy Cash. "I love it," she says of Cash's song 'Espresso Macchiato', "in German we call it 'Ohrwurm', which means you have it in your mind and you don't forget it." IMAGES AND SOUNDBITES
