I Trying To Find A Song - I'm Sorry The Msg Is Long - Help!

 usually come onto this site to find recent information on songs, so i thought that you know wot I'm going to join!

I'm REALLY SORRY WHAT I'm ABOUT TO TYPE IS LONG, BUT please READ!!!!
Anyways, I'm looking for a song BUT i don't know what its called or who sung it, I know, can u imagine!!

However, i remember in the video that this guy was talking to this girl and everytime he said a line she said = yeah, (next He sung another line) and she said - So (next line)she said -  Why (Next line) she said - Eh (next line) etc.
after that chorus, he took her to her parents and they were wearing traditional clothes (the ones in olden Yoruba films) and the setting was black and white but it was a modern video. The black and White look, was only to emphasise the past! That how much I can remember!
