Just repeat the chorus again

DAN: John, it's 4 AM, man. We've gotta stop writing this song. Let's just repeat the chorus again and go to sleep.
JOHN: NO!! It's gotta be something NEW, Dan! The BEATLES wouldn't "just repeat the chorus again"!!
DAN: The Beatles don't have an early shift at Kinko's tomorrow. JOHN: We don't sleep until we redefine the fundamental structure of pop music!
