Billy West (voice actor, Futurama, Ren & Stimpy, many more)
SPB: You've also played music in your past and you do some singing ("Shut Up and Love Me") in Futurama. How much creative say do you have when your characters create music?
West: Most of the music was always written for us and we sang exactly what Ken Keeler (writer,composer and producer) wanted.
I really didn't have much say in what my characters did except the acting choices. But on "Shut up and Love Me" they came up with the song title and I wrote the music and lyrics.
Beautifully puerile!
