A regular on the Great White Way in the 1950s and 1960s, Cook appeared in the original productions of Leonard Bernstein's Candide and Meredith Wilson's The Music Man, for which she won a Tony award in 1957.More news: Mom's hilarious back-to-school photo goes viral
Her Broadway career ended in the early '70s as she struggled with depression, alcoholism and weight gain.
Born in Atlanta in 1927, Cook always hated vocal exercises, never had a vocal coach and had an effortless skill of creating beauty by just opening her mouth. She is survived by their son Adam.
As her drinking spiraled out of control, Cook withdrew from show business.
Sondheim became one of her biggest champions. She returned to the stage in the '80s, playing Sally in a critically-acclaimed concert version of Follies at Lincoln Center in 1985.
