Viewers from across Europe tuning in to the first heat of the Eurovision Song Contest semi-finals, were left disappointed after a punk band from Finland, whose members all have learning difficulties, failed to qualify.

Finnish punks Pertti Kurikan Nimipaivat (PKN) were chosen to represent their country with the song Aina Mun Pitää, or I Always Have To, which broke a Eurovision record for being the shortest entry in the competition's 60 years.

The band members met through the Lyhty charity based in Helsikni, which supports people with developmental disabilities, BuzzFeed reported.

Kalle Pajamaa, a worker at Lyhty who helped to form the band, told the website: “Of course we want to show the world that disabled people can do and perform music as so-called normal people.”

But PKN were knocked out of the competition on Tuesday evening, along with Moldova, Netherlands, Macedonia, Belarus and Denmark.

PKN fans quickly vented their frustrations on Twitter, with some surmising that the band's 1.30-minute song was simply too punk for the show.

Instead, Albania, Armenia, Russia, Romania, Hungary, Greece, Estonia, Georgia, Serbia, and Belgium were chosen for the finals on Saturday.

Those nations will battle it out against the finalists who make it through the second semi-final on Thursday.
