"On and On" by Jimmy Martin tells the tale of a man traveling down a long, lonesome highway, feeling the pain of a lost love. He recalls the memories of their past love, but now they are saying goodbye. He continues to follow his darling, wondering where she may be, and if she ever thinks of him. Despite feeling heartbroken and crying for her, he feels as though he must continue on this journey to find her. His friends also love her and believe he is to blame for their breakup. In the end, he is determined to reach his destination by her side, even if it means traveling endlessly on and on. The song captivates the listener with its heartfelt lyrics and emotion-filled melody, expressing the longing and persistence of unrequited love.
