Best use of inset text, Snark Division:
You can find the title of this show rendered in different official places as Diana: The Musical; Diana, The Musical; and even Diana the Musical, as if Diana were either the name of the musical (like Garfield the Cat) or Diana were something you were encouraged to do to the musical (like Pat The Bunny). I have gone with Diana, The Musical.
