It is for 'One Shot'.
It was not shot in one shot.
It is basically the same as the 'Beat Again' video except slightly different.
You can watch it here.
There's some brilliant seriousface action from Aston throughout the video but particularly at the 2:51 point.
It includes some "bright dancing", the craze that swept the nation during the 2009 X Factor in spite of nobody actually a) doing it or b) really having a solid idea of what it was and c) it not actually sweeping this or any other nation in any way shape or form.
At the 2:52 point, Marvin does a 'cleavage reveal' just like the one in the Gabriella Cilmi video. So much for 'bright dancing' — cleavage reveals are where it's really 'at' in the world of the teen 'tribe'. (Except Marvin is not exactly a teenager any more and is an old duffer in boyband terms.)
That business with the magic microphones at the start doesn't really work, does it. It reminds us of this.
