From an EW story on Fisher’s death:
In her 2008 memoir Wishful Drinking, which she adapted from a one-woman stage show, she dished on her relationships with musician Paul Simon, whom she dated throughout the late 1970s, married, divorced, and dated again. Among his many songs believed to be inspired by her, the most undeniable was the title track to his 1982 album, Hearts and Bones, about “one and one-half wandering Jews” who have a passionate romance, but are destined for different lives. (Fisher is the one-half, since only her father was Jewish.)
