The Robert Hazzard "Girls Just Wanna Have Fun" is one of the more interesting ones so far, I think.
I had never been acquainted with that original version. Wow!
It's really interesting how compelling it can be, and how much it can change the meaning of the song to simply deliver it with a female lead as opposed to a male lead. Aretha, of course, demonstrated this with her cover of "Respect."
Whoever had the idea to have Cyndi do this song... wow, that was a masterstroke. Really cool. It kind of takes on a new dimension simply by knowing that the original exists.
