Just as I'd never eaten frog guts, I hadn't considered the trophy's religious undertones. The adversarial gamesmanship snowballed. Not content with just inter-school rivalry, we began billing the match variously as "the Irish against the Scots", "the Catholics against Calvinists", "Micks against the Presbyterians" and the unlikely "Rome versus Edinburgh". We reached for any motivation, real or imagined.
I thought back to that winter this morning after listening to Fijian rugby bosses again attempt to make a case for playing their banned military rugby stars at the World Cup. Their argument, to play rugby for rugby's sake, simply doesn't wash. Even as teenagers playing a team across town we couldn't extricate politics from sport.
Back in 1986, our 80 minutes of footy ended in a heartbreaking draw when a last minute St John's conversion attempt hit the post.
Today, a quarter century on and eight days out from the World Cup opener, the two schools will again square off for the Father Fisher Trophy.
This former Catholic dog will be sideline, vicariously playing, wistfully earning back his spot on the Papists' right wing.
Kick-off at St John's College, Hastings, today at 4pm. See tomorrow's edition for result.
