This song describes a famous guy who is abusive to one woman and drives another to suicide, all the while claiming he is not to blame. The likely inspiration is Jackson Browne, who Mitchell dated for a time. Browne's first wife Phyllis committed suicide in 1976, and Daryl Hannah accused Browne of hitting her during their relationship. Browne has vigorously denied the accusations, and no charges were filed.
