"Cross Your Heart" was the Irish entry in the Eurovision Song Contest 1974, performed in English by Tina. Tina performed all eight songs in the Irish national heats on RTÉ's Saturday evening entertainment series The Likes of Mike, where she sang four songs in English and four in Irish. The result was decided, for the first time since 1967, by a public postal vote in which "Cross Your Heart" won by a landslide with 16,686 votes, 11,000 clear of the runner-up "Is Liom É". It was succeeded as Irish representative at the 1975 Contest by The Swarbriggs with "That's What Friends Are For".
