Herreys, sometimes Herrey's or Herrey, is a Swedish pop group, consisting of the three brothers Per Herrey, Richard Herrey, and Louis Herrey. 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 17 years and 184 days of age, respectively. In 1985, they won the Sopot International Song Festival with "Sommarparty". At the time of their Eurovision win, the brothers were living and working as singers in Cleveland, Ohio, United States.
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.
The three brothers reunited to perform "Diggi-Loo Diggi-Ley" in the intermission of one of the Swedish Melodifestivalen semifinals of 2002.
