Year 2 World Music: Australia

I think we've listen to this song in class for at least 10 times (we designed a dance to it~) and children still haven't got fed up with it. They love the story behind the song and the melody was so easy to pick up. The only downside is that I can't use this song to introduce Aboriginal music. It'd be perfect if I can find a version with didgeridoo playing in the background.
