RentBoy - that's what it is. "Another" musical comedy but with a twist. It's not as dull as it seems. The book stands out and the "generalness" of it. To me, none of the songs or musical numbers were specifically memorable. What's memorable about the show are the performances and story. This doesn't mean the musical numbers were bad, they were very very good! They were just generally memorable instead of individually.
The stand-out number that I DO remember is the duet between DHP and the female interest.
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
--Aristotle
