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.
 It featured an orchestra and a chorus, as well as numerous soloists.
 More than 11,000 performers participated, including the famous violinist Ole Bull as the orchestra's concertmaster, and Carl Zerrahn as director of the choral forces.
 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.

"Ole Bull and Old Dan Tucker" is a traditional American song.
 Several different versions are known, the earliest published in 1844 by the Boston-based Charles Keith company.
 The song's lyrics tell of the rivalry and contest of skill between Ole Bull (named for Ole Bournemann Bull, a famous violinist) and Dan Tucker (title character of the blackface hit of the same name).
 The song also satirizes the low pay earned by early minstrel performers: "Ole Bull come to town one day [and] got five hundred for to play."
