Yeah, so apparently this has been out for some time. Someone just sent this to me over the weekend and it's the first time I've heard it. So I decided to throw it up on the site for those like me who may have not heard it yet. The only info I have on this is that it was unearthed by DJ Soul and appears to be more of a reference track than a demo.
It's quite possible they were still shopping for an artist to sing the hook, but who knows. I do dig the fact that they left a small snippet of the vocal from the original sample (Brenda Russell's awesome "A Little Bit of Love"), but something about Pun poking fun at his weight problems makes me a little sad.
