I've seen several it as well, I'm sure it was on The Box, and I do like the song, in fact I even found myself singing it today.
I'm not sure about the video, I agree it's better than David's, but some of the camera shots I find quite difficult to watch without starting to feel giddy.

I know that sounds silly, but I'm serious, there are a couple of times when I just have to look away.
I hope both Ainslies and Sineads song do well as I think they both deserve to.
