The song "Molly" by John Denver tells the story of a young man who leaves home and joins the circus in the hopes of finding success and making money. He is motivated by his love for Molly, who is waiting for him back home. As he enters the world of show business and experiences the bright lights and excitement of the circus, he realizes that he has not been able to save any money for Molly. However, he finds solace in the fact that Molly understands his situation and continues to write to him. The lyrics also touch upon the transient nature of the circus life, with references to riding box cars and the temporary joy that grease paint and smiles can bring. Despite his adventures and the distance between them, the young man holds on to Molly's letters, even though they are fading with time. He remains dedicated to his promise of returning to her and expresses his desire to close his eyes and be with her once again. Overall, the song reflects themes of love, sacrifice, and the longing for stability and connection amidst a nomadic and uncertain lifestyle.
