I'm obviously late to this party but I finally saw Andrew Rannells doing “I Believe” from “The Book of Mormon” on the Tony Awards in 2011. And wow:

Favorite parts/lines:

• The lookaway he gives at “What's so scary bout that?”
• The little nudge he gives the warlord on “...Jesus has his own planet as well.”
• The testify dance at the end, where he's the only one testifying.
• “And I belieeeve ... that in 1978 God changed his mind about black people!”
• “And I belieeeve ... that the Garden of Eden was in Jackson County, Missouri!”

I also like that the clunkier beliefs are embedded in clunkier lines. And how joyous it still is. 

P and I have tried to see “Mormon” a bunch of times but it's always sold out. But I believe that someday we'll have our own planet. Um, tickets.
