"Bryan O'Lynn", in Gaelic "Briain Ua Rloinn", also known as "The Banks of Lough Gowna", "Brian O'Lynn", "The Cockled Old Man", "Eamonn a' Chnoic", "Emon Acnuck", "Geese in the Bog", "Hitler's Downfall", "The Humors of Ballinafad" or "The Planting Stick" is an Irish double jig in A Dorian (Harker/Rafferty, Mitchell, O'Neill/Krassen) or A Minor (O'Neill/1850). The parts are played ABB (Mitchell), AABB (Miller & Perron, O'Neill). The alternate title "The Planting Stick" comes from a dance performed to the melody in the Province of Connacht which pantomimed the process of planting cabbages or potatoes with a stick. English morris dance tradition has a stylized imitation of the work in "Bean Setting". "Hitler's Downfall" is the title County Galway fiddler Martin Byrnes had for the tune. This is not related to the comic song of the same name. It was printed in Harker's 300 Tunes from Mike Rafferty (2005), Miller & Perron's Irish Traditional Fiddle Music, 2nd Edition (2006), Mitchell's Dance Music of Willie Clancy (1993) (appears as "Brian O'Lynn"), Krassen's O'Neill's Music of Ireland (1976), O'Neill's Music of Ireland: 1850 Melodies (1903), O'Neill's Dance Music of Ireland: 1001 Gems (1907), O'Neill's Irish Minstrels and Musicians (1913) (as "The Planting Stick, or Bryan O'Lynn"), Ryan's Mammoth Collection (1883) and Vallely's Learn to Play the Tin Whistle with Armagh Pipers Club, vol. 3. It was recorded by Patrick Street on Irish Times (1989), Kevin Crawford on In Good Company (2001) and Martin Byrnes on Martin Byrnes (1969) (appears as "Hitler's Downfall").
