In many club quizzes, the common question asked is: "What important football events took place in August 1959, 1961 and 1981?''
"Too easy,'' said football historian Norman McRobbie.
"Those were the years that Otago teams won the Chatham Cup, Northern in '59 and '61, plus Dunedin City in 1981.
"Not to forget Dunedin Technical, who won the trophy more recently in 1999 when they hammered Waitakere 4-0 at North Harbour, and striker Aaron Burgess got on the scorecard and also won the Jack Batty Cup for his dynamic performance in that final.''
Nostalgic nods usually follow those ancient revelations.
Recent performances in the cup have been less glorious, since Mainland's Cashmere Technical won in 2013 and 2014 and last year's winner was Eastern Suburbs, from Auckland.
However, in typical Otago longevity, Justin Flaws still played for Technical's first team last week, only 17 years after playing in the 1999 final and scoring against Waitakere.
Flaws is still an effective winger, with a more streamlined haircut than he used to sport, and he can still deliver deadly corner kicks when allowed by coach Tony Martin.
Technical plays Northern Hearts at Tahuna Park today with the traditional 2pm cup start, in case extra time and penalties are required.
More even encounters will have Queenstown Rovers at home to coach Richard Kerr-Bell's young Green Island side, and Grants Braes taking on Invercargill Old Boys at Ocean Grove.
FPL leader Caversham, which has conceded only one goal this season, should be too good for coach Lewis Houghton's Northern side, which has shipped more than three league goals per game (24) so far.
Roslyn-Wakari beat Mosgiel 3-2 in the FPL earlier in the season, but coach Colin Thom's team's form has dipped in recent matches and Mosgiel is on a high, which should make the Plainsmen favourites to progress.
University takes on the brave Mornington Lions from division two at the Caledonian Gground and coach Steve Ayoub might use history in his team talk, since Mornington, when combined with St Kilda, had a glorious cup run in 1965 before losing in the final.
More recently, Mornington sparked last year in the cup by beating Invercargill's senior side, Waihopai, 2-1.
In the Women's Knockout Cup, Northern plays Queenstown women in the curtain-raiser, at noon at the Caledonian Ground.
And in the 12.45 pm Women's Premier League, Dunedin Technical Premier plays University Women's B at De Carle Park, while top of the table University Premier plays Roslyn-Wakari at Logan Park.
