Okay, I have a problem with "information" on the web regarding who is credited for the theme music to "Diagnosis Murder" because I heard that music played on #NPR #FreshAir which re-aired a 1989 interview with #JohnnyOtis when they came to the topic of #HarlemNocturne .

Wikipedia and a wide assortment of other sources say that Richard Benedictis and Joel Goldsmith were the composers (not arrangers), while "Harlem Nocturn" was composed by Earle Hagan for the TV show "Mike Hammer". To my ear, they're both the same piece of music. What's up with that?
