...the movies...
I remember reading years ago that there was originally going to be a song sung to young simba by sarabi called 'lion in the moon'. I don't know how far it got into creation but i'm fascinated by how it would have turned out.
There's also warthog rhapsody, which was completed and I assume was replaced by hakuna matata. A good choice as hm was a much better song.
What else is there?
