For me, deffenately a fun disney song of some kind like Friend Like Me from Aladdin, Hakuna Matata from the Lion King, or the Gaston song from Beauty And The Beast. Those ones are great, and the Gaston song is hillarious.
I'd also probably sing Don't Stop Believing by Journey. Because that song is just plain awesome.
"Just a small town girl, living in a lonely world, she took the midnight train going anywhere. Just a city boy, born and raised in south Detroit, he took the midnight train going anywhere, a singer in the smoky room, smell of wine and cheap perfume, for a smile that can share the night it goes on and on and on and on. Strangers, waiting, up and down the bouylevard, shadows searching in the night, streetlight people, living to just find emotion. Hiding somewhere in the night. Working hard to get my fill, everybody wants a thrill. Paying anything to roll the dice just one more time. Some will win some will lose, some are born to sing the blues. While the movie never ends it goes on and on and on. Strangers, waiting, up and down the bouylevard, shadows searching in the night, streetlight people, living just to find emotion, hiding somewhere in the night. Don't stop believing, hold on that feeling, street light people, oh...don't stop believing."
