It's not going to happen again

I have known the most dear that is granted us here,
   More supreme than the gods know above,
Like a star I was hurled through the sweet of the world,
   And the height and the light of it, Love.
I have risen to the uttermost Heaven of Joy,
   I have sunk to the sheer Hell of Pain--
But--it's not going to happen again, my boy,
   It's not going to happen again.

It's the very first word that poor Juliet heard
   From her Romeo over the Styx;
And the Roman will tell Cleopatra in hell
   When she starts her immortal old tricks;
What Paris was tellin' for good-bye to Helen
   When he bundled her into the train--
Oh, it's not going to happen again, old girl,
   It's not going to happen again.
