[7] Morgan sang popular songs in nightclubs and small restaurants, and at bar mitzvahs and other private parties, to help pay her tuition expenses at Juilliard.

Morgan and Hilda soon opened a new weekly hour-long television show and she began recording in 1949 on the French Polydor label as well as Parlophone, Philips, and others.

She appeared in Can-Can, The King and I,[14] Kiss Me, Kate, Gentlemen Prefer Blondes,[15] Bells Are Ringing,[16] Anniversary Waltz, Affairs of State, Hello, Dolly[17] and others.

Morgan divorced Larry Stith in 1964,[19] and married Weintraub, more than a decade her junior, in 1965; the couple later adopted three daughters, Julie, Jamie and Jody.

[20] Morgan's two final albums were for RCA Records: her last LP, Jane Morgan in Nashville, yielded two moderate hits on the country music charts, including her answer to Johnny Cash's song, "A Boy Named Sue", titled "A Girl Named Johnny Cash" (written by comic Martin Mull).

[21] The only other time she had recorded without formal arrangements was on her hit single, "Fascination"; nevertheless, she was reportedly dubbed "The Countryest Girl in Nashville" by the crew.

[20] On December 10, 2009, she performed at the UNICEF Ball honoring her husband, Jerry Weintraub, held at the Beverly Wilshire Hotel, singing "Ten Cents a Dance" and "Big Spender".

[20] Her collection of her unique performance gowns spanning from the 1950s to the 1980s were exhibited to the public for the first time, premiering at the Brick Store Museum in Kennebunk, Maine, in February 2022.

She toured with Jack Benny and John Raitt, and appeared at the Grand Ole Opry; two of her RCA singles hit the Billboard country charts in 1970.

[citation needed] She starred in three of her own television specials: The Jane Morgan Hour (1959); Voice of Firestone: An Evening in Paris (1959), and The Jane Morgan Show (1968), and made several dramatic television appearances, including The Web: Rehearsal for Death (1952); Peter Gunn: Down the Drain (1961); and It Takes a Thief: The Suzie Simone Caper (1970).

[26] Morgan's version of "If Only I Could Live My Life Again" was featured during the closing credits of the second season finale of Apple TV's The Morning Show which was released November 19, 2021.
