The way in which the final song becomes the fourth-wall-collapse moment of the play. With that yearning, elegiac coda--where is the Juggler? (“And what exactly is a dream? And what exactly is a joke?” “Jugband Blues”).
And the hilarious Wise Man (“He's naked. Is that wise?”) which is none other than “Time” and its guitar solo, on the edge of trite. Yet very intense: the Wise Man's lesson, to the adolescent running the show, is “This…is not…a drill.”
The way Stoppard is an OOO playwright, refashioning existing play-objects. Expanding, remixing, remastering.
