"The Lark In The Morning", also known as "An Fuiseog Air/San Maidin", "Daugherty's Jig", "Road to Sligo", "The Trip to Sligo" and "When I Parted" is an Irish double jig or set dance in E Minor. The melody printed in O'Neill as "Lark in the Morning" is usually known in modern times under the title "The Trip to Sligo" while the "Lark in the Morning" title is usually reserved for another jig. However popular the jig has been in Irish tradition, it has a Scottish provenance, being the composition of Scottish fiddler-composer John Anderson who originally called it "When I Parted" and printed it around 1790. It was printed in O'Neill's Music of Ireland: 1850 Melodies (1903), O'Neill's Dance Music of Ireland: 1001 Gems (1907), O'Neill's Waifs and Strays of Gaelic Melody (1922) and Williamson's English, Welsh, Scottish and Irish Fiddle Tunes (1976). I learned it from Williamson's book.
