The 10 countries who qualified on Thursday night now compete for the Eurovision trophy alongside Belgium, Croatia, Finland, Greece, Lithuania, Moldova, Poland, Serbia and Sweden – who all qualified on Monday.
They’ll be joined by the UK, Italy, Germany, France and Austria – who receive automatic places in the final.
Austria gets a free pass because it won last year, and is hosting this year’s festivities. The others are members of the aforementioned “Big Four”.
You can tune into the grand final on BBC One, BBC iPlayer, Radio 2 and BBC Sounds from 8pm BST on Saturday night. And there’ll be full coverage, including a comprehensive live page, on the BBC News Website.
In preparation, you can download a Eurovision score card to record your opinions of the 25 finalists.
