Looking for a song
 

Hi,

I am going crazy over here, since I am looking for a song which I only remember the video to.
It is a song by an all male indie band (maybe british) and in the video the band is playing in a bar and there are different pairs of people there and these people start to dance very professional together suddenly. For example they first play pool together, than dance and suddenly go back to playing pool. And the song is also Kind of sad!
