Thrice Oscar-nominated Dory Previn Shannon, who helped pen the score for the film “Valley of the Dolls” and the theme for “Last Tango in Paris,” died Tuesday, Feb. 14, of natural causes at her farm in Southfield, Mass. She was 86.

Previn earned Oscar nominations in the 1960s for writing lyrics alongside then-husband Andre Previn’s music for the films “Pepe” and “Two for the Seesaw.” The couple were married from 1959 to 1970 and also collaborated on songs for movies including “Inside Daisy Clover” and “The Swinger.” She also drew an Oscar nom in 1971 for her work on a song from the film “The Sterile Cuckoo.”

Other film credits include the theme to “One, Two, Three.”

She won an Emmy Award in 1984 for co-writing the theme song for the TV show “Two of a Kind” and was nominated the following year for co-penning the theme song to the show “Two Marriages.”

She sang at Carnegie Hall, wrote a libretto for Mozart’s opera “The Impresario” and recorded many albums, including “Reflections in a Mud Puddle” and “Mythical Kings and Iguanas.” She also co-wrote with Previn “The Magic Number,” a work for voice and orchestra that world premiered with the New York Philharmonic in 1997, and penned a one-woman play with songs, “Schizo-phren,” through which she addressed her own struggles with mental illness. In 1983 Previn Shannon wrote “August 6, 1945,” a musical statement on nuclear war in which she appeared with Tyne Daly, Judd Hirsch, Thelma Houston and Bernadette Peters at the Mark Taper Forum in Los Angeles.

Dorothy Veronica Langdon was born in Rahway, N.J.

She is survived by husband Joby Baker, whom she married in 1984.
