Australian music history comes full circle in this special episode as Mark "Cal" Callaghan from GANGgajang joins Triple M's Dangerous Dave and Gleeso to celebrate Sounds Of Then (This Is Australia) being crowned Number 1 in Triple M’s Most Played Countdown.

More than four decades after its release, Sounds Of Then has once again captured the hearts of Australians, proving its enduring legacy as one of the most iconic songs in Australian music. Cal reflects on the unlikely, almost mystical origins of the track—written quickly, instinctively, and recorded on an early 8-track recorder in Kirribilli in 1982.

In a remarkable full-circle moment, Cal shares that he is now house-sitting in the very same Sydney location where the demo was first recorded, looking out at the same block of flats that inspired a song which would go on to define a generation.
