Do you all remember a show called "Where Are They Now?" on VH1? The premise of the show is self-explanatory, but they would have theme episodes and one was on the cast of "Grease."
I remember the piece they did on Charles: She worked as a sort of coach for men undergoing sex changes to become women and she would train them on how to walk, the correct posture so they could seem more "womanly." I just thought it was an unusual job for someone to partake, and thought it was cool she was helping some people get through a very daunting transition.
