"Blue Light, Red Light (Someone's There)" is a song by Harry Connick, Jr. that tells the story of a person living in a small and humble dwelling. The lyrics describe the protagonist's tight living quarters, a small closet-like space in a cold water flat. Despite the limited comfort, the person feels content because they know that someone is always there with them. The song emphasizes the individual's lack of concern about mundane things like climbing stairs or paying for transportation because they have the reassurance of companionship. This sense of comfort and security is further highlighted when the person takes up a job as a sweeper, ensuring cleanliness for someone else. The lyrics also express a hopeful aspiration for a better future. The protagonist dreams of moving uptown or even to the countryside with their companion, envisioning a life where every leaf on a tree represents the addition of another member to their family. They demonstrate that they would be satisfied with imperfect living conditions, haunted by supernatural figures, as long as they have their loved one by their side. Overall, "Blue Light, Red Light (Someone's There)" speaks to the power of love and companionship, suggesting that no material possessions or physical comforts can compare to the presence of someone who truly cares and is always by your side.
