Grime i.d.?

So bcuz (aside from dizzee and wiley albums) grime is v. hard to come across in cd shelves in the united states, my experience w/ the genre has mostly been filtered through the partial files and unlabeled downloads i've accessed through slsk. So - my question is about a song I heard last night at two in the morning when a friend of mine and i were driving down lake shore drive and suddenly this song came on his iriver and we both went nuts and i'm sure if a cop had been around we would have been pulled over.
Anyway, it was basically the "we finally got a piece of the pie" sample from i guess the good times theme. I know there was a hip-hop track from a few years ago called "whoa now" that used the same sample, but the beat to this was different and I don't remember who spit over it but it was very short, i think cut off.

Any help?

My bad, I meant the theme to the jeffersons, not good times.
