"You are the music while the music lasts. "
T. S. Eliot

I'm having fun shifting the emphasis in this statement:

You are the music while the music lasts.
You are the music while the music lasts.
You are the music while the music lasts.

If you and music are interchangeable, then what is your song?

And what will you do to make sure that your song lasts?
