First of all, I think it's about union and we have to remind all the world how united it was when the big invasion began," says Ukrainian rapper Aliona Savranenko, who, under her stage name alyona alyona and in a duet with singer Jerry Heil (real name of Yana Chemaieva), is representing her country at the 68th Eurovision Song Contest, which has been marked by controversy over Israel's participation in the midst of its offensive in the Gaza Strip. "Politics is everywhere", admit the artists, who are among the favourites in the contest and are using the platform to raise funds to rebuild a school. IMAGES AND SOUNDBITES
