There is a whole lot more to opera than just having a through-sung score.
Who is his director? Will he be his own libbrettist?
Often opera composers orchestrate and arrange the score themselves. Can he do this?
Now to get really dishy, I was chatting with one of Mr. Schwartz's collaborators, a reasonably well known name around town, who said "I'll never work with Stephen Schwartz again and you can quote me!"
"Hmm" I thought, "that isn't good."
"If my life weren't funny, it would just be true. And that would be unacceptable."
