Millions watch YouTube musicals

You know Cinderella — but "Cinderoncé"? She's retelling the classic tale set to the music of Beyoncé, on YouTube, where musicals (not the Broadway kind) are garnering millions of views. Most are short and wacky — "Super Mario 3D: The Musical" — but the production quality is pretty slick. A 42-minute teen musical called "Side Effects" even tackles the hard stuff (drugs, family, relationships).
