S-K-O, originally known as Schuyler, Knobloch and Overstreet, was an American country music group composed of Thom Schuyler, Fred Knobloch and Paul Overstreet. The original lineup recorded one album for MTM Records and charted three country hits, including the Number One "Baby's Got a New Baby". After Overstreet departed in 1987 for a solo career, he was replaced with Craig Bickhardt, and the group was renamed S-K-B. S-K-B released one album and four singles before disbanding in 1989.
