In December 1969 Tom McGrath, producer of the Irish National Song Contest, invited Scallon to try again next year, feeling that one of the entered songs, the ballad "All Kinds of Everything", would suit her. Her second attempt to win the Irish contest was a success. Then on Saturday 21 March 1970, the eighteen-year-old schoolgirl performed the song at the Eurovision finals held in the Amsterdam RAI Exhibition and Convention Centre, before an estimated viewing audience of two hundred million. Perched on a stool while wearing an embroidered white mini-dress, she was the last of twelve contestants to perform that night. After the voting had finished she was declared the winner with 32 points, beating the favourite, UK's Mary Hopkin, with 26 and Germany's Katja Ebstein with 12. Spain's Julio Iglesias came equal fourth with Guy Bonnet of France and Henri Dès of Switzerland. This was Ireland's first of a record seven successes in the contest.
