Like a putt on the 18th, the fifth penalty in a shootout or a last-minute drop goal, it all comes down to this.
Over the past four weeks the debate has raged: what were the greatest sporting moments of the first five decades of televised sport in Ireland?
Our pundits championed the athletic achievements of Treacy and O'Sullivan, they spoke powerfully on the political significance of England playing rugby in Croke Park and an Irishman winning the Tour de France, but in the end it was you the public who voted for our four finalists.
Tonight, at 10pm on RTÉ 2, you will decide what is Ireland's Greatest Sporting Moment.
Des Cahill and Evanne Ní Chuilinn will be joined by some very special guests but you can have your say now by voting below. In case you need reminding, here is another look at the four final moments.
Ray Houghton's goal against England at Euro '88
Munster beating the All Blacks in 1978
Padraig Harrington wins his first golf Major at the 2007 Open
