Ukraine's Eurovision winners celebrate 'important victory' for their nation br br 'The victory is very important to Ukraine, especially this year,' says Kalush Orchestra frontman, Oleh Psiuk, after winning the Eurovision Song Contest for Ukraine with an infectious hip-hop folk melody. The band received special authorization from Ukraine's government to attend Eurovision, since men of fighting age are prohibited from leaving the country, but that permit expires in two days. Psiuk said he was not sure what awaited the band as war rages back home.
