Whenever I see Wildhorn mentioned in this forum, the first thing that comes to mind (to me at least) is the vision of critics' knives sharpening even before his work is presented onstage. It's almost a Pavlovian reaction. Wildhorn has to make a living, just like anyone else. Who knows if "Casanova" will eventually make it to Broadway? But to dismiss that possibility outright (Mr. Roxy) is premature.
"Noel [Coward] and I were in Paris once. Adjoining rooms, of course. One night, I felt mischievous, so I knocked on Noel's door, and he asked, 'Who is it?' I lowered my voice and said 'Hotel detective. Have you got a gentleman in your room?' He answered, 'Just a minute, I'll ask him.'" (Beatrice Lillie)
