[Omkvæd] En sømand drog ud på en rejse så lang og bølgerne slog om hans skib Delfinerne sprang og kaptajnen sang “Du kommer sgu nok hjem engang”	[Chorus] A sailor went out on a journey so long and the waves hit his ship The dolphins jumped and the captain sang ‘You’ll damm probably make it home somehow’
[Vers 1] Men sømanden tænkte på pigen sin Og dagene blev til år Han tænkte, ja – jeg kommer nok hjem engang Men sig mig hvornår, hvornår	[Verse 1] *But the sailor thought of his girl And the days turned into years He thought, yes – I will probably come home somehow But tell me when, when
[Vers 2] Og pigen hun huskede den allersidste dans Mens dagene blev til år Så fandt hun endelig sig en elsker så blid Som gad at slikke hendes sår	[Verse 2] And the girl remembered the very last dance While the days turned into years Then she finally found herself a lover so gentle Who was willing to lick her wounds
[Vers 3] Og skibet det sejlede fra havn til havn Til sidst hun glemte hans navn Men tiden den går, som tiden den vil En dag lagde skibet til	[Verse 3] And the ship sailed from port to port In the end, she forgot his name But time goes on, as the time it wills One day the ship came into port
[Vers 4] Han tog en taxa til byens hotel Hun så ham og glemte helt sig selv De genså hinanden for en enkelt nat En nat på byens hotel	[Verse 4] He took a taxi to the city’s hotel She saw him and completely forgot herself They saw each other again for a single night A night at the city’s hotel
[Omkvæd] En sømand drog ud på en rejse så lang og bølgerne slog om hans skib Delfinerne sprang og kaptajnen sang “Du kommer sgu nok hjem engang”	[Chorus] A sailor went out on a journey so long and the waves hit his ship The dolphins jumped and the captain sang ‘You’ll damm probably make it home somehow’
