Interesting fact: A court drama surrounding the song "Kookaburra Sits in the Old Gum Tree" (commonly known as "Kookaburra") was a landmark 2010 Australian copyright lawsuit, Larrikin Music Publishing v EMI Songs Australia Pty Ltd. It found that the famous flute riff in the 1981 hit song "Down Under" by the Australian band Men at Work infringed on the copyright of the 1934 children's campfire song. Separately from this, there was a public outcry when a school principal tried to change the word "gay" to "fun" . (internet information)
