"The Greencastle Hornpipe", in Gaelic "Crannciuil Caislean-Glais/Glas", also known as "Limerick Hornpipe", "McPartland's Style" or "Spring Garden Hornpipe" is an Irish hornpipe in G Major (Allan, O'Neill) or D Major (Roche, Lamancusa) and AB (Moylan), AA'B (Moylan) or AABB (Allan, O'Neill, Roche, Lamancusa).
The hornpipe is contained in the large mid-19th century music manuscript collection of County Cork cleric and uileann piper Canon James Goodman as an untitled tune. Reg Hall (1998) says the tune has had enough currency in Northumberland to be considered local. County Leitrim flute player John McKenna recorded the tune in New York in 1925 under the title "McPartland's Style" (honoring a renowned step-dancer). The first strain of "Greencastle" is somewhat of a 'floater' and versions can also be found in "Hanley's Hornpipe" and "The Mountain Hornpipe".
Francis O'Neill learned the tune from a young Limerick man named James Moore in Chicago during the winter of 1875. Moore, a flute player without an instrument, lived in a cold boarding-house across the street from O'Neill and often availed himself of O'Neill's hospitality, ensconcing himself on a "cozy seat on the woodbox back of our kitchen stove" while borrowing O'Neill's flute to play on. Moore, complained a frustrated O'Neill, often did not remember the names of the tunes he played ("a very common failing"). O'Neill lost track of him when he moved to New York in the spring.
