The earliest known appearance of this air in print is in the second volume of The Scottish Minstrel (circa 1811), under the title “Kelvin Water”, although the tune is probably much older. The present arrangement for two flutes is taken from Blake's Young Flutist's Magazine, published in Philadelphia in 1833.
This is the eleventh piece from 24 Etüden zur Förderung der Technik (24 Studies for the Development of Technique), Op. 12, by German flutist Emil Prill. It was first published in Bremen in 1913.
This air is taken from Francis O'Neill's collection Waifs and Strays of Gaelic Melody, published in Chicago in 1922. O'Neill had the tune from O'Farrell's Pocket Companion for the Irish or Union Pipes (published between 1804 and 1811), and remarked:
The name of a ballad sung to this air has been substituted for “The Young Man's Dream” an obviously wrong title — as printed in O'Farrell's work.
