The song "Walk On" by John Hiatt tells the story of a person walking through the streets of New Orleans. The lyrics depict a scene where someone calls out to the protagonist, sounding distressed and desperate. Despite being in a place where nobody knows their name, the protagonist feels a sense of euphoria in the sweet air and their spirit feels uplifted. The song describes the steam rising from the sidewalks after an evening rain, creating a hazy and intense atmosphere. The heat feels more suffocating, as if it's closing in on the protagonist. They continue walking up St. Charles Street, possibly towards a destination or to catch a streetcar named "Desire," referencing Tennessee Williams' famous play. In the midst of their walk, the protagonist encounters a young couple fighting or struggling in a doorway. The man seems to be forcing or pressuring the woman. This distressing scene is juxtaposed with the sound of gunshots in the distance, adding to the tense and dangerous atmosphere. The chorus, "Walk on, walk on, Don't look back, Don't ask questions, Don't you try to understand," suggests that the protagonist is advised to keep moving forward and not dwell on the situations around them. They proceed back to their hotel room where someone special, referred to as "she," is waiting for them. The protagonist is plagued by fear and worries about losing love, which drives them to rush back to their partner. They reflect on their own fear and wonder if the struggling couple saw that fear in them. Overall, the song delves into the raw emotions present in a bustling city like New Orleans. It explores the themes of fear, desperation, and the need for love and connection amidst a chaotic and unpredictable world.
