Y is for Your Mercury Mouth
In Sara on the Desire album, Dylan says he stayed up for days in the Chelsea Hotel writing Sad-Eyed Lady of the Lowlands for her (With your mercury mouth in the missionary times and your eyes like smoke and your prayers like rhymes). They had separate rooms in the Chelsea Hotel, in order to keep their relationship secret.
Sara Dylan, known as Sara Lownds, met him while driving round Greenwich Village in her MG sports car. She was Dylan’s first wife and mother of singer Jakob Dylan and of director Jesse Dylan. They were married at a secret ceremony in November 1965 until a bitter divorce in June 1977. It was not public knowledge for years, but he depended on her for advice on everything.
A fictionalized account of their marriage is featured in the Bob Dylan biopic I'm Not There, with Heath Ledger playing Dylan and Charlotte Gainsbourg playing Sara Dylan.
Beside Sara and Sad-Eyed Lady, she also inspired many of the potent tracks on Blood On The Tracks, and Isis, We Better Talk This Over, Abandoned Love, Down Along The Cove, Wedding Song, On A Night Like This, I’ll Be Your Baby Tonight, If Not For You and Love Minus Zero/No Limit.
