In the late 1960s, singer-songwriter Joni Mitchell and musician Graham Nash were involved in a brief romance that terminated with a symbolic telegram from Mitchell. Mitchell subsequently channelled experiences from the relationship into her acclaimed 1971 album 'Blue,' which featured compositions interpreted by listeners and critics as autobiographical reflections of their connection.

Three tracks stand out as likely portraits of their relationship: 'My Old Man' explores Mitchell's reluctance toward marriage following Nash's reported proposal; 'River' conveys the emotional toll of separation, with Mitchell acknowledging her own contribution to the breakup; and 'Willy'—using Nash's middle name—captures romantic loss. In subsequent interviews spanning decades, Nash confirmed these songs faithfully documented their experience together, characterising the relationship as intense yet ultimately devastating for him.
