So I listened and read, but I really don't see prostitution as a (let alone
the) clear theme in the lyrics in the Andrews Sisters' recording. It seems more about bars and calypso music. The closest to prostitution is the verse about a couple spending the night together and the next morning relaxing in the sun. Point Cumana was (and may yet be) a beach resort in Trinidad.
Ah,
this Wikipedia article is informative. The version of the lyrics recorded by the Andrews Sisters had been re-written by Morey Amsterdam at a couple of key lines. I doubt DU-folk would care that their faux-outrage-of-the-moment is misplaced; OTOH, I doubt the several Andrews Sisters' estates much care about DU-folks' outrage, either.
