My most favorite Carl Sims song of all times is "Seventeen Days of Loving" and if you go back through my blog (the easiest way is to google Southern Soul Paradise Carl Sims), you'll see that he has recorded tons of great music. "It's Just A Party" is so smooth and it showcases how versatile Carl Sims is. This is nice and I think you'll really like it.
The Marvin Sease music he sampled for this is right on the tip of my tongue - it'll come to me soon...
