The brains behind the John Farnham Voice ad - ABC listen

The co-founder of the advertising agency behind the latest Yes campaign ad said they "knew they were onto a winner" when they learnt they had permission to use John Farnham's You're the Voice in the ad. 

The latest ad, authorised by the Uluru Statement from the Heart, is the first time the iconic anthem has been allowed to be used in a commercial.

Mark Green, co-founder of The Monkeys advertising agency who made the ad, and Clare Wright, Professor of History at La Trobe University, who came up with the idea, joined Virginia Trioli to discuss how the new ad came to be.
