In some ways, what I learned is that you can take a character and breathe with them, and its up to the audience to interpret rather than you putting moral stamp on the character.
My father's a musician and my mother's a singer. My dad's originally from Brooklyn and he was a Latin percussionist so I've always had instruments around the house. He used to have a show like a 1950s rock and roll show with Little Richard music. They would do doo-wop songs and stuff like that.
