To celebrate St. Patrick’s Day and to pay tribute to Mabel Normand during Women’s History Month, we feature this shamrock-bearing sheet music cover for “Molly O (I Love You).”

The song was written for the 1921 film Molly O’, based on Mack Sennett’s tender love story of an Irish girl’s struggle to overcome her lowly beginnings. Mabel Normand plays Molly O'Dair, the penniless daughter of an Irish washerwoman and a ditchdigger who falls in love with a millionaire bachelor.
