The dress rehearsal was the last chance for the first 16 semi-finalists to perfect their performances, before a private show in front of the Eurovision decision panel.
And Eurovision fans have plenty to look forward to with bright lights, smoke machines, pyrotechnics, graphic backdrops, colourful costumes, not to mention some catchy tunes.
This has been the first taste of Eurovision 2014 for the more than 2,500 cast and crew members who make the show a reality.
It's known for bringing together fans from all over the world, despite world politics and tensions.
And after rumours of a boycott, Ukraine is now seen as a real contender.
"I didn't change my decision because I wanted to take part in Eurovision and I didn't even think to refuse of it." Ukraine performer, Mariya Yaremchuk said.
The contest is expected to draw a worldwide audience of more than 180 million viewers, including Australians.
Iceland's "Pollaponk" has been likened to Australia's brightly coloured man band, The Wiggles.
"We had never heard of the Wiggles, but we have now and we like the Wiggles" said members of Pollaponk.
But it's Australia's own, Jessica Mauboy, who many are excited to see.
Jessica's Eurovision journey from Darwin to Denmark is almost complete.
This is the third time Denmark has hosted the contest – the first time was in 1964, and then in 2001.
