In the 1991 movie, Rush, uncredited radio DJ Name?

In the first minutes of the movie Will Gaines is driving away from The Driller’s club in his Mercedes, a DJ is on the car radio…who voiced the DJ?  I’ve lived in SE Texas my whole life, I am 99% certain it was an actual Houston radio DJ voicing that part, which one?  What was his on-air moniker?  What station was he at?  Where is he now?
