This is the first and only episode which features a nightclub that is not Janette's The Raven. Whereas The Raven always features Lori Yates or Molly Johnson songs (and on occasion United State's), this club only played disco music.
With this episode, Lisa Ryder made her first guest-starring appearance in the show as Angela Mosler in the flashback. She would go on to become a cast regular in Season 3 as Detective Tracy Vetter.
The flashbacks are implied to take place in the 1960s or early 1970s, based on Lacroix referring to their time period as "The Age of Aquarius."
