Looking at comments on Long Time Ago and the thread Going Home, these comments may help. The Shaker song "Simple Gifts" and George Pope Morris' "Long Time Ago" (thanks again to those on this thread) are two of ten arranged by Copland in his "Old American Songs." Others came from minstrel, sacred and other sources. The best renditions are on Thomas Hampson's cd. Not all the notes on "Going Home" are correct. Dvorak's symphony 9, "From the New World", includes this melody which is his alone. ALL the words were fitted later. He was at the Rochester School of Music at this time, hence "From the New World." (Humor here as well?, since the food, girls and booze area of Prague at that time was known as the "New World"). Vaughan-Williams used many folk tunes. See the classics-based "Penguin Guide to Compact Discs", pub. by Penguin Books, for titles of his folk song arrangements.
