This was clearly the weakest performance I've heard him singing. Fortunately the semi performance has no bearing on the final results, but he really needs to control his nerves - I'm assuming it was that, because he sang well in the second half, but that won't get him anywhere in the final.
Hopefully he'll be able to deliver a solid performance on Saturday (like the ones we've been used to see), and then we'll just have to see where it'll take him.
Despite this probably being the best composition in the contest, I don't quite see it winning - but before you jump on me, I can't see anyone winning right now and someone has to take it anyway. Interesting times!
