In 1979, four sisters from Philadelphia, Kathy, Kim, Debbie and Joni, took the world by storm when they released a disco anthem that celebrated their family.

Today, these sisters are working on a gospel album dedicated to their mother and encouraging a new generation of Sledge women. "What's so amazing is we have five aunts, five aunts in the first generation, five of us, and now we each have a daughter," Kathy says, "And there's a new Sledge group!"
