Mansfield is probably best known by American audiences as the composer of the tune "Funky Fanfare", used for underscoring in NFL Films productions and the Astro Daters series of snipes produced by the National Screen Service in the late 1960s.
That song is currently used during the opening credits of the show Pit Boss on Animal Planet, as well as backing music for the "Quick Hits" segment on the Sklarbro Country podcast.
Mansfield also composed the brass tune "Superstar Fanfare", which was notably used (in several variations) by Channel Television in the Channel Islands, RTL plus's news programme 7 vor 7, Worldvision Enterprises, and by the Services Sound and Vision Corporation (SSVC) as a idents jingle for British Forces TV in West Germany, Berlin, Cyprus, The Falkland Islands and Gibraltar in the 1980s and 1990s.
American sports fans will find a lot of Mansfield's and other KPM composers' music used on NFL Films team highlights and Super Bowl documentaries.
American sports journalist Jon Bois uses Mansfield's work ("Love De Luxe", "Style City") in his videos.
