"O'Dwyer's Reel", in Gaelic "Seisd/Cor Ui Duibidir", is an Irish reel in D major. The parts are played AB (O'Neill/1850 & 1001), AA'B (O'Neill/1915 & Krassen). Some phrases are reminiscent of "The Devil's Dream". The first strain reappears as the 'A' part in Bayard's Pennsylvania-collected "Cheat River". Both this tune and that are related to "Soldier's Joy" and "Come Dance and Sing". It was printed in O'Neill's O'Neill's Irish Music (1915), O'Neill (Krassen) (1976), O'Neill's Music of Ireland: 1850 Melodies (1903) and O'Neill's Dance Music of Ireland: 1001 Gems (1907).
