It's always been popular here. In fact, there was a sit-down in Houston in the 80s.
And, it toured through Texas a lot in the 80s, I have 3 or 4 playbills from different companies in different cities, and my parents went to see the tour at one point. And, it's done every 3-4 years by at least one company in the Dallas-Fort Worth area.
The Ann-Margret tour I know came to Dallas, and I want to say they even got Marvin Zindler to play himself during the Houston run (although, that could have been a separate production).
The show really isn't controversial, and most people, when you mention the Chicken Ranch, know at least the story.
