Ira Newborn (sometimes credited as James Ira Newborn) seems to have built a film music career from the scoring of light-hearted comedies, although it has to be said that some of these comedies have a deep side to them too, and his output includes some scores for other genres. Not only has he scored the Naked Gun series based upon his TV theme for Police Squad, but he has also had a significant involvement in the movies of people like Steve Martin, John Candy, Jim Carrie and Dan Aykroyd, including for the latter the musical supervision and conducting honours for the iconic Blues Brothers movie.
You might say that the Dragnet and Police Squad themes emerge from a parody of the mood set by Henry Mancini's Peter Gunn theme, also used in the Blues Brothers movie. The theme for Dragnet itself uses a four note motif borrowed from a "Film Noir" movie called "The Killers" scored by Miklos Rozsa.
Most of these albums include a mix of film score and song tracks, so please check the details before buying.
