If they changed it to "Darn Yankees," then nobody would've seen it, because they thought it would be a parody of the show.
The only issue then was the kind of innuendo or content about a specific person, like "got the lady high" has a different meaning now, much like "rape" does in FANTASTICKS. I do know "Blonde and stacked and absolutely bare" was changed, but I just don't know what they changed it to.
Anyway, if anyone wants to do "THE FANTASTICKS", and people are sensitive to the word "rape," then they might as well do "It Depends On What You Pay" with the lyrics they have in the current production:
"We've the obvious open school-boy chase
With little mandolins and a fast embrace", etc.
