The lyrics were written by Mogens Mogensen and the melody is borrowed from the English folk song " Geordie" with very slight alterations. "Langebro", named for a bridge of the same name in Copenhagen, is one of Gasolin's most popular songs.in The lyrics give an insight to the darker side of society in Copenhagen. Gasolin' was concerned about the poor and helpless and this was often reflected in their lyrics.
