Is the landlord talking about the same music as the brass March? That's called ant March. It was originally a children's song, but it was often changed into a March as military music. It also appeared in the picture of several troops marching in the movie "Born on July 4th". However, it is almost impossible to find the orchestration and arrangement version as in Die Hard Rowen Rowen 3. I've been looking for it for a long time. Only on the soundtrack.
