No one has ever looked more relaxed and comfortable. Sitting on a sofa sipping tea, he is a formidable, familiar figure, happily taking stock of his life against the backdrop of a Sydney recording studio.

All that could cause a commotion here are the amplifiers, the microphones, the mixing desk and, of course, the man himself. Peter Garrett has come home.
