This episode features the famous "Magnum P.I." music theme as a background. It won't become the main theme until episode 12.
The familiar Magnum, P.I. theme is heard for the first time in this episode, on the closing credits as well as variations in the incidental music during the story. Written by Mike Post and Pete Carpenter, who have recorded numerous other themes, such as The Rockford Files and The A-Team, this theme would soon become the series' main theme, replacing the original one by Ian Freebairn-Smith that is used on the very early episodes. The seemingly never-ending 'looped' edit of the new theme used on this occasion was only used on one other episode, on the closing credits of "Don't Say Goodbye" later in the season
