Finished this in the nick of time!
This week I was inspired by a video my boyfriend showed me (who, like me, has a soft spot for all things cute) of a cockatiel singing 'If You're Happy And You Know It...'
You can watch the video here: http://youtu.be/U9NZnpleU0s?t=30s
Too cute! So here is an equally vocal cockatiel, singing something a bit more challenging.
