Whats the name of this song and who sings it?

Question

In the music video for this song they have a black guy break dancing the whole time and there are people standing around watching him explaining why he dances so much.. Apparently its to bring back his girlfriend who left him and in the end she comes back.

Oh yea, some of the chorus goes like this: "days gone by I cant live my life without you, without you, without you"
