Radio Telefís Éireann (RTÉ) held the national final on 8 February 1976 at its studios in Dublin, hosted by Mike Murphy. Eight songs took part, with the winner chosen by voting from eight regional juries.
On the evening of the final Hurley performed 7th in the running order, following Belgium and preceding the Netherlands. At the close of voting, "When" had picked up 54 points, placing Ireland 10th of the 18 entries. Ireland received one maximum 12 from Italy, which the Irish jury reciprocated by awarding their 12 to the Italian song – oddly, neither country received a maximum vote from any other national jury.
