"Stir It Up" is the second single from Patti LaBelle taken from the soundtrack album to the 1984 film Beverly Hills Cop -- the latter won a Grammy Award for Best Album of Original Score Written for a Motion Picture or Television Special (1986).
The single is also the second of a couple of songs (the other being "New Attitude") she recorded for MCA Records immediately after signing her new contract with that company. Her first full-length album for MCA, Winner in You, would follow the next year.
The song was also used as the theme song to the short-lived sitcom Stir Crazy, based on the 1980 hit movie.
The music video features Patti LaBelle singing the track in a recording studio with session musicians. This intercuts with a young woman running through the streets. She recruits other passers-by who follow her to the studio where Patti is singing. The city shots were filmed in New York.
