The Catholic Archbishop of Melbourne caused a bit of a stir last year when he banned pop music and football songs from funeral services.

Justin Gregory talks to Archbishop Denis Hart, church historian Peter Matheson, Wellington Cathedral Music director Michael Fulcher and Parachute music director Mark de Jong on how to pray through music.
