"Nocturne" was the winning song in the Eurovision Song Contest 1995, performed in Norwegian by Secret Garden representing Norway. It was the second time Norway won the contest, after it had won in 1985 with Bobbysocks! song "La det swinge". For their performance at the Contest the Secret Garden duo of Fionnuala Sherry and Rolf Løvland featured two guest musicians; Norwegian vocalist Gunnhild Tvinnereim and Swedish nyckelharpist Åsa Jinder.
The victory represented the second for composer Rolf Løvland, who had previously written "La det swinge". Additionally, it represented the first time in four years that Ireland had not won the Contest, thus bringing to an end the only hat-trick of victories in Eurovision history. Ireland would go on to win the next Contest, achieving the feat of four victories in five years.
As Norway had previously won the Contest in 1985 with "La det swinge", the second victory allowed the tongue-in-cheek tradition to emerge that Norway could only win in years ending with a 5, a joke referred to by the members of Bobbysocks at the Congratulations special in late 2005, Norway having entered "In My Dreams" that year and not achieved victory.
The song is noted for its relative absence of lyrics - with only 24 words being sung in the original Norwegian version and much of the rest of the song being given over to a violin intermezzo performed by Irish musician Fionnuala Sherry.
While no other victorious song has featured so few words, Finland would go on to place 15th in the 1998 Contest with "Aava", which contains only six words repeated throughout the song. The previous holder of the record of shortest lyrics in Eurovision history was Belgium and their 1983 entry "Rendez-vous", with a total of 11 words.
"Nocturne" was not released as a single in Norway itself. The first release of the song as a single would come in a comedic cover version by country-inspired novelty band Dusty Cowshit, reaching #16 on the Norwegian singles chart in 1996. The song was however released as a single by Secret Garden in the rest of Europe and Scandinavia, then in its English language version, and reached #26 in Sweden, #6 in Belgium (Flanders), #24 in Belgium (Wallonia) and #20 in the Netherlands.
"Nocturne" is included in Secret Garden's first album, Songs from a Secret Garden. The album "Inside I'm Singing" (2007) includes a new version.
