“All Night Long” was an international smash hit. It topped the Billboard Hot 100, R&B and Adult Contemporary charts in late 1983 and also reached the top 10 in several countries overseas.

Writing the song took months, as Richie was unable to come up with a chorus until a Jamaican gynecologist uttered, “I’m going back to work all night long.”

Ever wonder where people got the idea that everyone in the 1980s dressed like a crayon doing cardio? Well, this song’s video is a pretty good place to start.
