Donny Osmond has announced that he will return to play Gaston in the final Broadway performance of Disney’s Beauty and The Beast. I’m guessing that performance is already sold out, although there is no mention of it in the article.
John Tartaglia, whose show "Johnny And The Sprites" is a big Disney Channel favorite in this house, is currently playing Lumiere. The rest of the current cast includes: Anneliese van der Pol as Belle, Steve Blanchard as the Beast, Stephen Buntrock as Gaston, Jeanne Lehman as Mrs. Potts, Jonathan Freeman as Cogsworth, Jamie Ross as Maurice, Meredith Inglesby as Babette, Mary Stout as Madame de la Grande Bouche, and Aldrin Gonzalez as Lefou.
