The Greig-Duncan Folk Song Collection from northeast Scotland, was the work of the schoolmaster and musician, Gavin Greig (1856–1914), and the minister James Bruce Duncan (1848-1917). The project began in 1902 and was completed between then and the First World War. Its largest contributor was Bell Robertson. A selection of the songs was published in 1925 under the title Last Leaves of Traditional Ballads and Ballad Airs collected in Aberdeenshire by the Late Gavin Greig.
