Yes, Sally Duncan is still alive. Her most recent act was in the Law & Order: Special Victims Unit December Solstice (Season 16, Episode 16) which was aired on February 25, 2015. She played the role of Judge Virginia Farrell.
Actress/comedienne/vocalist Sandy Duncan's climb to show business' upper echelon did not come easy. The star of a popular situation comedy, Funny Face, from 1971 until early 1972, Duncan had her career come to a near stop when surgery, for a tumor on the optic nerve, left her blind in one eye.
Undeterred by her handicap, Duncan resumed her career with the same determination that had taken her from her birthplace in Henderson TX to Broadway, movie, and television fame. Although Funny Face, which was renamed the Sandy Duncan Show upon Duncan's return in autumn 1972, was canceled after the season, Duncan remained one of America's most flexible entertainers.
The recipient of an Emmy award for her performance in ABC-TV mini-series, Roots in 1977, she returned to Broadway to star in the revival of J.M. Barre's Peter Pan. After limiting herself to rare television appearances for nearly a decade, Duncan starred in the sitcom the Hogan Family from 1988 until 1991. She appeared in a touring revival of Chicago in 1999.
