Also, another teaser video has been released by LadyGaGaVEVO - her official YouTube page

It's very similar to the first but there are some different shots at about 0:08 onwards, at first I thought it was just a fan who'd mixed the video up, but there's tonnes of new footage and we still get a glimpse of Lady GaGa and her circles, this time right at the end of the video.
The sound is different too, this time the sounds feature more of the original song.

The video was released at the stroke of midnight last night.

So, that's a teaser video for the stroke of the 3rd June, one for the stroke of the 4th, who's gunna pull an all-nighter for the third video? ;)
