Meaning

“All Night Long” was a single by funk/disco group the Mary Jane Girls. The group was actually a ploy by Rick James to get one of his back-up singers JoJo a record deal. Aside from JoJo, the other members of the group couldn’t sing which led to their demise in 1987 and JoJo going on to a solo career.

“All Night Long” has been sampled many times in hip hop including LL Cool J’s “Around the Way Girl,” Jay-Z’s “Only a Customer,” Big Daddy Kane’s “Smooth Operator,” Ice Cube’s “You Know How We Do It” and Redman’s “Tonight’s da Night,” “How to Roll a Blunt” and “Can’t Wait” in which they also appeared in the video.
