Adam-12 Square (let's make it happen! Moorpark and Tujunga!) was used as a location on the anthology series Police Story, season 1, episode 18. Even more entertaining, the "Reed" character was played by Smokey Robinson. Yes. Smokey Robinson.
While Adam-12 was Jack Webb's show of admiration and support for the LAPD and done by Universal, Police Story was police officer turned writer Joseph Wambaugh's look at the tormented lives of officers and done by Warner Brothers. [Note for non-Angelenos: Universal and Warner Brothers are basically kitty corner across the LA River and Barham Blvd. There's some "terrain" in between, but they're neighbors.] Police Story overlapped in time with Adam-12 beginning in 1973. Both series were on NBC.
Police Story was an hour-format and much more "adult." Like Adam-12, they went outside and showed you the actual city. Thank you! Much of Police Story showed downtown Los Angeles, and of course the area near Warner Brothers too. This episode, "Wyatt Earp Syndrome," must have been a nod to Adam-12, as actors Cliff Gorman and Smokey Robinson (!) are 1-Adam-19 and eating at Adam-12 Square. Presumably they would have attended the same roll call as Malloy and Reed! [And like Malloy and Reed, being in "Central Division" led them to Henry's Tacos in Studio City for 7.]
The red barn-looking "delicious sandwiches" place seems to have changed names since it was "The Fire House" (sometimes one word, sometimes two!) The Shell station on the southwest corner was 4399 Tujunga. The simply named "Valley Stores" at 11418 Moorpark and its liquor sign have held out since the days of Adam-12 patrolling Adam-12 Square, and the market was usually listed as North Hollywood, despite this technically being Studio City. Businesses at the time were mostly considered North Hollywood.
Police Story captured Lakeside Market right before its end. And yes, there is another "Six Degrees of Adam-12" connection. I'm guessing most people would say Lakeside Market was in Toluca Lake. Others might think Burbank (which is a separate city; Toluca Lake is part of Los Angeles). But it used to be listed as North Hollywood! And look whose wife had submitted a recipe! It's our pal Dick Whittinghill, who made an Adam-12 appearance ("Reason to Run") and loaned his Studio City home out for the lady-shot-her-husband call in "Log 56: Vice Versa." The Valley's "Finest Families" -- an elitist supermarket in the Valley. In North Hollywood. Indeed!
