Just to clarify, this isn't a leak. This is officially released on the bands SoundCloud page, but as you can see it is a very different mix.

On the SoundCloud upload it is titled "Nine in the Afternoon (Single Mix)", but it is NOT the same as the Single Mix on the album, and its not the Radio Mix either. This is almost a minuet shorter than both of those version. This is just an mp3 rip of that version. Just thought I'd post this here to give this weird version a bit of love!
