Roy will often begin his commentaries "sotto voce" as a mocking parody of Sydney radio announcer Alan Jones, but often finishes screaming at the top of his lungs. By his own account, Slaven has represented Australia in every known sport for most of the 20th century, has ridden in every Melbourne Cup (and won most of them) on his ageless mount Rooting King, is on intimate terms with every major sports, TV, music and film personality in modern history, as well as being a close personal friend of many top racehorses and greyhounds.
