Get ready for more GL musical hilarity in Ep III. I read (on the official site was it?) recently in an interview with GL that he realized we haven't had a stunning song and dance number in the prequels yet, so look for that in Episode III.

That ought to fit in REALLY nice with the republic being overrun by a tyrant, and our hero being burned alive in a volcano, only emerging alive and converted into the most purely evil being in the galaxy. Oh, and being torn from his secret wife and newborn children too. Damn, we really need some singing and dancing in that story.

I think the dark side is growing in that goiter of his.

And here's the relevant text:
With the prequel trilogy lacking in elaborate musical numbers, Aaron McBride and the rest of the Art Department were given the task to create visuals for a new spectacular in Episode III.
