The Old School Jam Of The Moment is "Return Of The Mack" by Mark Morrison. Mark was huge overseas but due to trouble with the law, he could not perform in the United States at the height of his success.
His vocal delivery was compared to Cameo's Larry Blackmon. The full 7 minute version still gets play in my Ipod, if in my car, or working out or.... wherever.
Hope you enjoy The Old School Jam Of The Moment.-DocFB
