I've only seen XANADU of those mentioned, but XANADU was ***AMAZING*** and one of the very few shows that I have seen more than once. Sit on stage, if you can.
I heard great things about CYRANO. Sounds like a winner.
"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
