The hymn originally appeared in the second edition of Songs of Praise (published in 1931), to the tune "Bunessan", composed in the Scottish Highlands. In Songs of Praise Discussed, the editor, Percy Dearmer, explains that as there was need for a hymn to give thanks for each day, English poet and children's author Eleanor Farjeon had been "asked to make a poem to fit the lovely Scottish tune". (...) "Bunessan" had been found in L. McBean's Songs and Hymns of the Gael, published in 1900. Before Farjeon's words, the tune was used as a Christmas carol, which began "Child in the manger, Infant of Mary", translated from the Scottish Gaelic lyrics written by Mary MacDonald. The English-language Roman Catholic hymnal also uses the tune for the Charles Stanford hymns "Christ Be Beside Me" and "This Day God Gives Me", both of which were adapted from the traditional Irish hymn St. Patrick's Breastplate. Another Christian hymn "Baptize In Water" borrows the tune. Piano arrangement by Rick Wakeman. http://en.wikipedia.org/wiki/Morning_Has_Broken
