Did you know that Cyndi Lauper's 1983 hit "Girls Just Want to Have Fun" was originally written and performed by the late Robert Hazard in 1979? While the lyrics were almost identical, the original version was sung from the perspective of a Don Juan and included an additional verse that Cyndi Lauper scrapped when she reworked the song and its theme into her classic '80s feminist anthem. It's pretty interesting how one song with virtually the same lyrics can tell two entirely different stories and convey vastly different messages.
