never settled down anywhere, and second, why the protagonist tried to solve these problems himself instead of calling in the police. Casting a doctor as the protagonist also provided the series a wider "range of entry" into local stories, as Kimble's medical knowledge would allow him alone to recognize essential elements of the episode (e.g., subtle medical symptoms or an abused medicine), and the commonplace doctor's ethic (e.g., to provide aid in emergencies) would naturally lead him into dangerous situations. Musical score Pete Rugolo, who had worked on David Janssen's earlier series Richard Diamond, Private Detective, composed the original music for The Fugitive. (Rugolo later worked with creator Roy Huggins on Run for Your Life and other projects.) Tracking music was standard practice at the time, but unlike virtually all primetime scripted series of the 1960s, no episode – not even "The Judgment" – received an original score; all the original music used for the series was composed by Rugolo and recorded in London before the series was filmed. In fact, many episodes had Rugolo as the sole credited composer for the episode's scores, but only a fraction of all the music heard throughout the series was original Rugolo music. Library music (either from other classic TV shows or from stock music libraries, as was the case with The Adventures of Superman) provided a majority of the episodes' scores. For example, Dominic Frontiere cues became common in season four; a keen listener could find oneself listening to such cues from the Outer Limits series during the climactic final episode of The Fugitive. Numerous ominous, dramatic, and suspenseful cues from The Twilight Zone episodes such as "The Invaders", among others, are used to strong effect throughout the series. The old pop songs "I'll Never Smile Again" and "I'll Remember April" each appear several times in the series, often associated with Kimble's deceased wife, Helen. What little original melody was actually written and recorded was built around a fast-paced tempo representing running music. Different variations, from sad to action-oriented, would be used, with many arrangements developed for the music supervisor to select as best suited for particular scenes. Also, an original "Dragnet"-type theme was used for Lt. Gerard. In the unreleased longer version of the show's pilot, a different (canned) music score was used in the opening and closing sequences. Also, several deleted scenes were shot, including one, with Lt. Gerard talking
