I'm actually not sure whether this famous television theme track was ever released as a single or not. Regardless, it's the melody that put Henry Mancini in America's households, and his LP of Peter Gunn music was a huge hit. Ray Anthony actually had the pop hit with the Peter Gunn theme in 1959. After this, Mancini went on to become a powerhouse in the movie soundtrack business, writing one movie theme after another, most of which managed to become pop hits. I've read that Peter Gunn (if you don't think you know it, that's cause you never put the music to the name... it's incredibly famous and familiar) was the first TV show to feature a jazz ensemble such as the one Mancini composed this music for. If so, that's equally interesting, because that means this is the model for all the dozens of similar shows that flooded the airwaves in the 1960's: "Mission: Impossible," "Man from U.N.C.L.E.", "Secret Agent," "The FBI," and so on.
