• This rollicking rocker finds Case taking on the subject of gender roles:
  
  "I'm a man's man, I've always been.
  But make no mistake what I've invested in.

  Case told The Guardian: "I think I just want balance. I want to be equal parts man and woman, no matter what I am at the gynecologist."
