Starsky and Hutch were police partners and best friends, but they would never directly call each other by their first names - except in two disco scenes in two episodes where they're introducing each other. The other episode being Discomania (1978).
The villain's name in this episode is Stryker, the same name as the villain in the season 1 episode, Snowstorm.
When Huggy Bear (Antonio Fargas) calls Hutch (David Soul) to ask him to go alone and see him at "The Pits", you can hear a few seconds of "Miss You" by The Rolling Stones.
The song the Starsky brothers sing after their night on the town is "I'm a Loser" by the Beatles, from their 1964 album "Beatles For Sale".
