Who are O Torvald?
The Ukrainian rock bank was first formed in 2005, with the current line-up hitting the big time when they were chosen to be the home act in this year's contest.
They'll be making full use of their home country's staging too, with a giant robot head dominating the arena.
Sadly, the gory digital clocks that seemed to be buried in their torsos during the official video (above) appear to have been dropped.
What's the Ukraine Eurovision song called?
The song is called Time, and was written by members of the band Halych Yevhen and Miziuk Denys. The chorus at least makes them sound pretty confident...
Time to look
Time to see
Time to find
Time to look into your eyes
Time to find truth
Time against the lies
Time will give us a sign
I can make a promise
It's our time to shine
