People listen to music with cavemen ears: Is it a bird song or the call of a lion? The audience at a musical is dancing in their hearts.

If someone wants to say 'I love you' in a straight play, they say it, and then it's the other person's turn to talk. But in a song, you can sing about it for another three minutes. The musical form has that unique opportunity to express at length what joy really feels like.

Write about the thing that frightens you most.

When ''night, Mother' opened, I did not know how long it would be before I would have another show on Broadway.

In the theater, when people hear that you're writing a play, they want to know what it's all about, whether there's a role for them. You write it fairly quickly, and it becomes a group activity before you're really ready to have company.

Knowing is the most profound kind of love, giving someone the gift of knowledge about yourself.

My view is that musicals are love stories with great final scenes. It's just that simple. Musicals are also conflicts between two worlds. And by those criteria, 'The Color Purple' is actually exactly the kind of story that makes for a great musical. Yes, it's got hard stuff in it, but so does 'Les Miserables' and 'Phantom of the Opera.'
