I have a screenplay that relies heavily on a Billy Joel song. The rising action involves discussion of one of his songs as an entree into discussing broader issues that are crucial to the plot. I don't know how far I can go without getting permission to use this song. How do I send Billy Jpel a copy of my screenplay for permission? I know this sounds like I'm a total novice, which I am, but it's a good script...witty and incisive. I reckon it's got legs.
