There was a pop song a few years ago (around 2000 - 2005) which had a music video with three black guys and three black girls singing a song in a carnival, and there were hats and masks involved.

Sorry but I can't remember any lyrics.

I don't know why, but it sounds like a video from 'big brovas'?
Sound familiar?

Ah, thanks, found it, it was indeed Nu Flow by Big Brovaz ( http://www.youtube.com/watch?v=OI5TDaYXkWg ).

Ah I thought that might've been the one :) no worries at all.
