Among those who went on to fame from this show are: Fergie of the Black Eyed Peas (real name: Stacy Ferguson), Martika (real name: Marta Marrero), Mario Lopez, Shanice (real name: Shanice Wilson), and Jennifer Love Hewitt and Eric Balfour (Six Feet Under).
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.)
Following the filming of the 1989 season the show was put on hiatus for two years, with the series picking up again in 1991. Only two stars from the 1989 season - Jennifer Love Hewitt and Kenny Ford - returned to continue production (hence the sudden change in the cast list at this time).
