I agree with Bobbin. I'm not that impressed by his vocals but it's hard to judge the quality of his singing by a clip that's just 15 seconds long. I'm actually glad to finally hear him sing in one of the videos.
Edit: I just listened to it again and the lyrics sound a little dull to me. I wonder if it is really something that's going to be on the album or a joke.

The melody reminds me of his "David, David, oh David" song.
