To make a song is a gift, and once it's done it keeps evolving and changing and becomes a tool to interact with other people. It's like a conversation.
What we do every night is we change out the set list as much as we can to make sure that (fans can) go home and tell their friends they experienced something unique and cool.
I don't want to sit and cry for an hour in a movie. I'd rather have an action or a comedy.
