"The Norwegian lyrics for Oleanna were written in 1853 by Ditmar Meidell, a newspaper editor in Norway. He set his words to a melody known as "Rio Janeiro". Theodore C. Blegen included the song in his 1936 book Norwegian Emigrant Songs and Ballads, which had the original lyrics, a literal translation by Martin B. Ruud and musical notation.[2] Eight years later Blegen himself wrote a singable translation consisting of 22 verses."
