Among those who went on to fame from this show are: Fergie of the Black Eyed Peas, Martika, Mario Lopez, Shanice, Jennifer Love Hewitt, and Eric Balfour.
During her time on "Kids Incorporated" Stacy eventually went from being the youngest to the oldest.
Jennifer Love Hewitt was not the original actress cast as Robin. Partway through the filming of the 1989 season, the original actress was released and Hewitt was given the role (perhaps explaining why she was one of the few characters to not share their name with the actor playing the role.)
Stacy Ferguson is the longest running cast member of Kids Incorporated, appearing in the pilot and six seasons.
Following the filming of the 1989 season the show was put on hiatus for a year, with the series picking up again in 1991. Jennifer Love Hewitt and Kenny Ford were the only ones from Season 6 who returned to continue production. Hence the sudden change in the cast list at this time.
