Matt Schichter is a filmmaker based in Glasgow, Scotland.

In Canadian radio, he was an announcer and music director, before he took his skills across to the screen - acting, producing and directing.

He's also one of the world's first podcasters, he started in 2003 before the word podcast was invented.

Mary-Lou Stephens is a best-selling author.

She's written Australian historical fiction novels "The Last of the Apple Blossom" and "The Chocolate Factory" and a memoir "Sex, Drugs and Meditation". All of them have received rave reviews from the media and fellow authors alike, and her latest work, "The Jam Maker" is out now.

But Mary-Lou spent quite a bit of time behind the mic, both on stage singing and playing in bands, then at radio stations 2TM, Mix Townsville and on ABC Radio in Queensland's Sunshine Coast.
