This moody mid-tempo rocker shows off the strong British rock influence that informed a lot of Kiss' early material. The lyrics take direct inspiration from "Fire Brigade," a U.K. hit for the Move, as they chronicle a young man whose passion for a tempting young lass is strong enough to be explosive: "Get the firehouse/'Cause she sets my soul a-fire/Get the firehouse/'Cause the flames keep getting higher." The music has a feel reminiscent of early Led Zeppelin or the Rolling Stones' heavier songs as it places an accent on lascivious, swinging rhythms in its verses and choruses. Kiss' recorded version benefits from a tight arrangement that pushes the song's pop hooks to the fore: Paul Stanley and Gene Simmons make great use of their falsetto harmonies over a bluesy hard rock backing that goes through plenty of twists as it layers low-slung guitar riffs over a throbbing beat. Ace Frehley also chimes in with one of his trademark stuttering-note guitar solos, and the song's cheeky feel is completed by fire-engine sound effects on its fade-out. All these touches added up to a fun rocker that has become an enduring staple of the Kiss live show, usually accompanied by warning lights and a live fire engine siren at its climax.
