Hip-hop track from 1989 or earlier (US?)

[garx]

I have two tiny fragments of this track.
83405
It was sampled in two tracks from 1989 (one from US and one from UK).

could be The Dynamic Guv'nors - These Guys Are Doper Than Dope

or they are sampling the track you want

Yeah, I'm trying to find which track Dynamic Guv'nors had sampled.
This 1989 house tune seems to sample the same track: https://youtu.be/mXpkavyIups . These are two tracks where I took these two fragments from.

Solved. It's The Union - The Union (from M. Walk Productions Featuring The Union LP, 1989)
