The Russian entry has been written and composed by an international team and now it's been revealed Rui Andrade will join the Tolmachevy Sisters on stage as a backing vocalists, who's Portuguese. Rui came 3rd in the Portuguese national final although he still gets the chance to shine in Eurvosion. ;-)
Meanwhile, with all the current problems in Crimea - what will happen when people there vote? Will the vote be counted as part of the Russian or Ukrainian vote? It'll be interesting to see how that develops.
