She was featured in Playboy magazine a few years later, in 1971 at the age of 35, in a pictorial entitled "Frantastic!". Ten years later she posed a second time for Playboy at the age of 45. This second pictorial was titled "Still Frantastic!"
"Sex and the Single Girl" was released on MGM in 1964 as a single and an LP. In 1966, Fran Jeffries recorded an album for Monument Records, This Is Fran Jeffries.
In 2000, Jeffries released a recording All The Love, again a collection of standards.
