You're On! de Malvina Reynolds

Why, why, why,
I'm asking why, why, why!
What's the use of,
What's the sense of,
What am I doing here?
Before we start
I've got no heart to speak or sing,
But suddenly I'm on.
We're all one thing, one thing,
And I am blended into you,
There's nothing left of aching me,
That used to cry, Why?
