Debut nation Moldova will open the show on the piano, with last time's winner, Norway, closing with the violin.
The running order was decided by host broadcaster WDR together with the Eurovision Young Musicians Steering Group, in order to separate out similar instruments and musical tempos throughout the show.
The live show begins at 20:00 CET on Sautrday 31 May. Tomorrow, we will bring you a full list of broadcast channels and times for this year's competition! You can also watch live online through our WebTV player!
