Sullivan played Polly Peachum in Marc Blitzstein's English-language adaptation of The Threepenny Opera by Kurt Weill and Bertolt Brecht off-Broadway in 1954. She also appeared as herself in an "original special" on Broadway, called Let's Make An Opera, which boasted music by Benjamin Britten, a libretto by Eric Crozier, musical direction by Norman Del Mar, and was directed by Marc Blitzstein. In the summer of 1951, she played Dorothy Gale in The Muny's production of The Wizard of Oz, opposite Margaret Hamilton, who reprised her film role of the Wicked Witch of the West. In 1992, Loesser's daughter, Emily, played the same role at The Muny, marking the first time in The Muny's history that a role has been played by both mother and daughter. Loesser later reprised her role in the 1953 production at the Kansas City Starlight Theatre. She married Frank Loesser on April 29, 1959, just ahead of the May 1, 1959, deadline that Sullivan had given Loesser to marry her "or she would carry on with her career and forget about him." They had two children, Hannah and Emily, who is also a singer-actress. She also appeared on numerous recordings, such as Loesser by Loesser as well as several albums for Ben Bagley's "Revisited" series on Painted Smiles Records. In the early 1980s, she resumed her performing career when officials of The Ballroom, a nightclub in New York City, asked her to sing some of her late husband's songs. After that, she performed at other night clubs and in several theatrical musicals. In 1984, Loesser developed a revue, Jo Sullivan Sings Frank Loesser and Friends, that was presented in several cities. From the time of her husband's death in 1969 until her own death in 2019, she managed his estate, particularly Frank Music Company, which included guiding production of all of his musicals, including Guys and Dolls, How To SucceedIn Business Without Really Trying and The Most Happy Fella. The publishing portion of the company was sold to CBS Records in 1976.
