Would the drunk driving PSA have been shot around the same time, and utilized the cantina set built for the HS?

The makeup on the bartender seems similar to one of the new characters made for the HS.
Interesting idea, but it’s not the same set. I’m guessing they just mocked one up on the fly, ala the Cantina pick-up shots done for the movie. The commercial apparently aired in 1979, so the time period is right for them to have used anything left over from the Holiday Special, but I guess they didn’t. They captured the hazy look and seedy feel of the Cantina far better than the Holiday Special did, though!
Funny to see how they utilized crappy plastic ice cream sundae cups all over the bar, though!
