Oleanna (Oleana) is a Norwegian folk song that was translated into English and popularized by former Weavers member Pete Seeger.
 The song is a critique of Ole Bull's vision of a perfect society in America.
 Oleanna was actually the name of one of Ole Bull's settlements in the New Norway colony of Pennsylvania.
 His society failed, and all of the immigrants moved away since the dense forest made it hard to settle there.
 The lyrics concern the singer's desire to leave Norway and escape to Oleanna, a land where "wheat and corn just plant themselves, then grow a good four feet a day while on your bed you rest yourself."
The National Peace Jubilee was a celebration, organized by Patrick Gilmore in Boston on June 15, 1869.

 The Jubilee became the "high-water mark in the influence of the band in American life".
 Along with the World's Peace Jubilee and International Musical Festival in 1872, it made Gilmore a famous composer and bandmaster.
 For the Jubilee, a newly commissioned "Hymn of Peace" was written by Dr. Oliver Wendell Holmes, set to the music from "American Hymn" by Matthais Keller.
