Our second-last guest this week is Award-winning musical comedian Gillian Cosgriff, joining Macca and Paul live on air to talk about her current show at the Melbourne International Comedy Festival.

Gillian Cosgriff’s here to talk about life. Not just her life. Not just your life. Life as a concept. And time. As a concept. We’re living in an age of relentless productivity, where every second should be optimised. We’re also outsourcing our questions to technology more than ever. But you know who has lived experience of being alive? Other people!

With original songs, existential questions and the kind of clever, lyrical joy only Gillian can deliver, Life, Oh Life is musical comedy for anyone who’s interested in life advice from people who have actually lived.
