Hello Susan-Marie,The United Methodist Hymnal © 1989 lists seven hymns in the index as having Native American Sources. Of the seven, only two can be heard here because of copyright. They are #244, 'Twas in the Moon of Wintertime and #378, Amazing Grace (which has words in Cherokee, Navajo, Kiowa, Creek and Choctaw). If this helps, remember about a contribution to the Mudcat! ;-)
