I bet the confusion stems from GIRL CRAZY being set in Custerville, AZ...the show originally contained a song, that didn't make it into CRAZY FOR YOU, called "Cactus Time in Arizona."
Yes, I knew Girl Crazy had been set in Arizona, and I just assumed Crazy For You had been, too. Even though I've seen Crazy For You, I either didn't notice the change of locale or had forgot about it.
