This episode marks the first of many regular appearances of Coroner Woody Strode, played by Kurt Fuller.
This episode's theme song is sung by Boyz II Men, an R&B group consisting of four black males singing mostly a capella - just like Gus' group.
In the flashback of the episode, Henry Spencer (Corbin Bernsen) mentions the TV show L.A. Law (1986) as another passing fad. Bernsen starred on "L.A. Law" decades earlier.
Gus mentions Blackapella once performed at a cinnamon festival. Shawn and Gus go to a cinnamon festival in Dual Spires (2010). Additionally, this is the third time a cinnamon festival is mentioned in an episode.
