She didn't produce SEUSSICAL. She stepped into the role. The show didn't flop because of her - it was because no one really gave it a chance.
I know many people who haven't seen the show, but LOVE the cast recording. It didn't get its audience in time. But when Cathy Rigby toured it, the show got a makeover, and it became 150% better! I wish THAT production went on Broadway.
"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."
