You have to be truly old school for this movie. If you know this movie than I'm sure this is one of your favorite movies. Before Dreamgirls, The Temptations Movie and The Five Heartbeats. There were Sparkle.
Irene Cara, Lonette McKee and Dawn Smith known in the movie as: Sparkle, Sister and Dolores. For the soundtrack they were replaced with the one and only Queen of Soul Aretha Franklin to bring a bigger name to the movie. However many fans of the movie were upset. Fans never got the soundtrack they wanted (although I love Aretha Franklin versions of the songs). All songs were written by Curtis Mayfield.
Later En'Vogue would come in the 90's and pay tribute to the movie Sparkle with their remake of "Giving Him Something He Can Feel" with their video.
Here is the movie version of "Hooked On Your Love"
