I've said it a few times before, but Ireland is another of those countries where the visuals look a lot better in the hall than on screen. It is very dark and my first association when I see it like this is an artic sea with icebergs in it, all be it that they are black in this case as well.
The balloon is still there and still adds nothing to the performance, other than it being a prop that people may remember it for. I hope in a good way though..
Vocally it seems ok in the hall, but it'll all depend on how it sounds on tv and of course on how well he will sing during the jury final and semi-final.
