Herreys ( ) , sometimes Herrey 's or Herrey , is a Swedish pop group , consisting of the three Mormon brothers Per Herrey ( born 9 August 1958 ) , Richard Herrey ( born 19 August 1964 ) , who is no longer a Mormon , and Louis Herrey ( born 3 November 1966 ) . They won the Eurovision Song Contest 1984 with the song " Diggi-Loo Diggi-Ley " . Richard and Louis Herrey became the first teenage males to win Eurovision and remain the youngest ever male winners , being 19 years and 260 days and 18 years and 184 days of age respectively . In 1985 , they won the Sopot International Song Festival with " Sommarparty " . At the time Herreys won Eurovision , the brothers were living and working as singers in the United States . 2 Herreys continued to record and tour for a few years , but had no hits of the same magnitude as the Eurovision winner . They were the first European boyband preceding the international boom a few years later . Herreys was the bestselling pop group in Sweden in the 1980s , and enjoyed enormous success touring and performing in excess of 300 live shows . Herreys was also the first western band to be invited to tour behind the Iron Curtain in the Soviet Union , and also did shows with the big Russian star Alla Pugacheva . Louis Herrey decided in 1987 that he needed to serve a mission for the Church of Jesus Christ of Latter-day Saints and with his brothers ' permission he left for two years , leading to the breakup of Herreys
