Rolf Harris was an Australian musician, television personality, painter, and actor. He often used unusual instruments like the didgeridoo and the Stylophone in his performances, and is credited with the invention of the wobble board. He was convicted in England in 2014 of the sexual assault of four underage girls, which effectively ended his career.

The didgeridoo is a wind instrument, played with vibrating lips to produce a continuous drone while using a special breathing technique called circular breathing. The didgeridoo was developed by Aboriginal peoples of northern Australia at least 1,000 years ago, and is now in use around the world, though still most strongly associated with Indigenous Australian music. In the Yolŋu languages of the indigenous people of northeast Arnhem Land the name for the instrument is the yiḏaki, or more recently by some, mandapul. In the Bininj Kunwok language of West Arnhem Land it is known as mako.
