"How Can I Keep from Singing?", also known as "My Life Flows on in Endless Song" is a Christian hymn with music written by American Baptist minister Robert Wadsworth Lowry. The song is frequently, though erroneously, cited as a traditional Quaker or Shaker hymn. The original composition has now entered into the public domain and appears in over 100 hymnals as well as other song collections, both in its original form and with a revised text. Doris Plenn learned the original hymn from her grandmother, who reportedly believed that it dated from the early days of the Quaker movement. Plenn contributed an additional verse around 1950, which was taken up by Pete Seeger and from then on by other folk revivalists. Though it is not, in fact, a Quaker hymn, twentieth-century Quakers adopted it as their own and use it widely today. Seeger's version omits or modifies much of the Christian wording of the original\ and adds Plenn's verse. The reference in the added verse intended by Seeger and by Plenn (both active in liberal causes) is to the activities of the House Un-American Activities Committee (Seeger himself was sentenced to a year in jail in 1955 as a result of his testimony before the Committee, which he did not serve due to a technicality). Most folk singers have followed Seeger's version. It was published in the Quaker songbook Songs of the Spirit and the original words, with Plenn's verse, were included in the much more ambitious Quaker hymnal project Worship in Song: A Friends Hymnal in 1996. It was printed in Pete Seeger's Bells of Rhymney. It was recorded by Pete Seeger on I Can See a New Day, Gordon Bok, Ann Mayo Muir, & Ed Trickett on Turning Toward the Morning (1975), John McCutcheon on How Can I Keep From Singing? (1975), Noel Paul Stookey on Band & Bodyworks (1979), Enya on Shepherd Moons (1991), Peter, Paul and Mary on In These Times (2003), Judy Collins on Portrait of an American Girl (2005) and many others.
