The performance at the London promotional event: x12s
I may not be a musical expert, but nevertheless: the vocals seem near perfect to me.

At the end, after the song is finished, you can see that Zoe is touched and overwhelmed by the reaction of the audience, she almost cries a little.
...and then she adds a little "encore" (chorus a cappella):
On the wiwibloggs channel there is a review video now:
William and Edd are amazed by the song and by Zoe (although they're uncertain about qualification for the final), Deban and Denise are not so pleased (song would be outdated, staging too colourful as seen in the official video and the national final).
The more I hear and see from the Austrian entry, the less I can imagine that this might eventually not go through to the final.
