The 2004-05 tour was indeed to be her last. It was BOTH a 100th Anniversary Tour (and 50th Anniversary of the musical) as well as her intended Farewell Tour.
THEN she did the show again at a regional theater (Pittsburgh CLO) a couple seasons ago and realized she missed the role. So she decided "hey, I'm still young...why not?!" So she's got her tights and is taking back out on the road.
Good for her.
But I would still love to see the Stiles/Drewe PETER PAN on stage here in the States...
"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
