Broadcast on the Triple J radio station to simulcast with the annual three-game rugby league State of Origin series, Australian comedians Roy and HG (played by John Doyle and Greig Pickhaver) provide a commentary of the match at hand.
A unique deviation from the usual format of the Triple J State of Origin coverage occurred in Game One of the 2007 Series, when Roy Slaven was unavailable to be present for the commentary.
A lengthy introduction to State of Origin rugby league is given by "King Wally Otto in the Soundproof Booth" (a pseudonym for well-known Australian voice-over presenter Robbie McGregor).
This introduction, which can last for 5 minutes or more, features King Wally Otto enthusiastically reading an elaborate Doyle and Pickhaver script, which more often than not culminates in a list of Former Origin Greats ("F.O.G.s"), and anecdotes about their achievements or foibles.
Taking his role of the 'sports announcer' of the pair, HG Nelson thanks King Wally Otto in the Soundproof Booth, welcomes listeners to their State of Origin coverage and provides further build-up to the game at hand.
With many media commentators declaring the concept of State of Origin dead after such one-sided results, Roy contacted Wally Lewis for his thoughts on the upcoming series, to which he replied "oh, are they still playing that?"
At approximately 8:00pm the players enter the field and line up for the singing of the Australian national anthem; an occasion which provides one of Roy and HG's most infamous twists on traditional sports commentary.
The choice of this song probably is due to the opening lyrics "When a boy becomes a man..." (signifying young players 'stepping up' to the challenge of State of Origin football) as well as the inherent violence associated with the former-boxer, Rose.
Before the beginning of State of Origin I 2008, because the buildup to the game had been quite emotional as Jack Gibson had recently died, a violin solo of "Waltzing Matilda" was played during the national anthem, with both Roy and HG applauding the 'beautiful' rendition.
By their own account, Roy and HG's commentary of the match is broadcast live from a card table adjacent to the halfway line of the playing field.
This expensive technology, which had notably poor picture quality, often could not keep up with the flow of play was over-used by Channel 9 during the broadcast, was frequently blasted by Roy and HG for disorientating them with the "telecast from the lunar surface."
