If the song is already written, sure, easy question. But say you're sitting down to write The Lion King before any composers have even been brought aboard, before pre-production has even been dreamt of. What do you write?
<Insert song here about a life philosophy precluding worry or anxiety and focusing on happy times, preferably revolving around a made-up word like 'haboona-tratata'...characters will romp around the jungle while main lion grows older in montage sequence>
How is this situation handled?
