Gary Barlow & The Commonwealth Band [feat. Military Wives] - Sing
 

This is gorgeous. A real feel-good song, I really love the chorus.

Gary and Andrew Lloyd Webber wrote it IIRC, and they travelled to different Commonwealth countries to film the video.

I am in love with this song at the moment, listening to it right now.

Have to say the chorus sounds very familiar, the first time I heard it I felt like I already knew it for some reason.
