Of the two turntable samples in this track, one is known to be Earth Wind and Fire "Getaway", where he's singing "I know we can, I know we can". The other is variously interpreted as a voice saying "what's happening" or even "David Addison". That sample has always bothered me, because I had a feeling that wasn't "spotted" correctly. I'm now 100% sure I've found what it really is... I've been messing around with FL to try and get slam-dunk proof but my sample-fu is weak, so maybe someone can do a better job than me.
If you grab the sample from Sixtyten, there's a clear one at 3:29, and flip it into reverse, you can hear that it's another sample from a vinyl pulled backwards. In the foreground you've got the notes BoC are playing, try and ignore them, and in the background behind the voice you can hear a quite trebly note - if you use that as a reference pitch, and try and unwarp the speed of the sample, the vocal becomes even clearer.
And we don't need to look too far to find where they got it: another song off the SAME Earth Wind and Fire album called "On Your Face". The lyric is "Keep a smiling face" but you only get "Keep a smiling..." before the pitch runs down too far. It shows up in all the choruses, there's a good one at 2:26 (see http://www.youtube.com/watch?v=hKwilkWC_uM ) The note in the background is the brass there.
I'm guessing this album has some kind of significance for them if they've pulled two samples out of it for the same song?
Edit: Here's my best shot at filtering out BoC's synths and stabilising the pitch.

Edit2: Ugh, that's a pretty crappy download page. Sorry about the 45 second wait thing. I don't have hosting at the mo.
Edit3: Corrected the name of the track with the sample in
