Australian Story this week profiles Morris Stuart, a charismatic choirmaster who takes a group of women from central Australia to Germany on an unlikely and remarkable road trip.

This episode is introduced by film critic David Stratton.

"When he suggests things I just think he's crazy sometimes," Rob Borgas, friend.

"He can teach a song in five minutes, it's quite astounding," Barbara Stuart, wife.

When Morris Stuart arrived in Alice Springs he was at a loose end.

The retired pastor and choirmaster had travelled reluctantly to the outback at the urging of his artist wife.

Not one to stay idle, he walked down the central mall and approached locals to see if they wanted to join a choir. Within a year Morris moulded the 50 amateur singers into a top-notch choir.

Word soon spread to the Aboriginal community and particularly to groups of women who liked to sing. They wanted Morris to turn them into a proper choir too.

But then a remarkable thing happened.

They sang their own songs for Morris, German hymns they'd been taught by their elders, the musical legacy of German missionaries from the 19th century who travelled to the red centre.

"I was astonished when I first heard them singing those songs. It was almost like a central desert secret," said Morris when he heard their repertoire.

Then came a crazy idea - what if they took the songs back to the place from where they had come?

So began an unlikely and inspiring trip from the deserts of central Australia to the cathedrals of Germany, a trip that changed the lives of each and every one of them.

When the body of Mark Haines was found on the train tracks near Tamworth in 1988, police quickly dismissed any idea of foul play. But after a 5 year investigation, journalist Allan Clarke believes he may have found the truth.
