After already scooping up several Tony Awards, The Book of Mormon kept the faith going on Tony night with an inspirational musical number. Best Actor in a Musical nominee Andrew Rannells, who plays Mormon poster boy Elder Price, put on his best short-sleeved missionary button-down to showcase the musical’s Tony-winning score with the moving and hilarious Mormon anthem, "I Believe." Can you believe this number is actually spouting real Mormon beliefs? Believe it, people! (And click on to see Andrew Rannells knock it outta the park!)
