Mark Colvin like you've never heard him.

In 1978 the ABC’s renegade youth broadcaster Double Jay premiered an audio experiment called, What's Rangoon to you is Grafton to me.

Almost 40 years later, we got back on the Pacific Highway to make a tribute to this landmark Australian radio road trip.

To cut a complicated story short, we roped highly respected, ABC icon, Mark Colvin into narrating the adventure.

Mark wholeheartedly supported our lofty ambitions and we're sharing it now in tribute to him.
