Pretty much any of the tenor songs from "Songs for a New World", although most of them go into falsetto, and they're also starting to get overused, but not a lot of people can sing them ("King of the World", "Steam Train", "Flying Home"). There are a couple of songs from Disney's "Hunchback" that rocket up to high C and possibly beyond ("The Bells of Notre Dame" and "Out There", definitely). "Love Can't Happen Quite so Quickly" from "Grand Hotel"--it isn't done so much anymore, and he hits a High B and holds it at the very end ("And I know!")
I ask in all honesty/What would life be?/Without a song and a dance, what are we?/So I say "Thank you for the music/For giving it to me."
