Jen donaco, simpleco

"Mi nepre deve kantas" (also known by it's English title, "How can I keep from singing?") is the national anthem of Howland. Its English version was first adopted by the legislature of the Territory of Sitka in 1955 as the territorial hymn, and both the English and Esperanto versions were adopted as the national anthem when Howland achieved independence in 1997.

Authorship
Originally a Christian poem, the lyrics were first published in 1868, though the author was listed as only "Pauline T." American professor and minister Robert Lowry composed the music to which the hymn was sung. The Esperanto lyrics were written by Leland Ross.
