Oddly, I have yet to encounter a variant of the tune "Larry O'Gaff" or its spawn "Daniel O'Connell", "Humours of Whiskey" or "Squid-Jigging Ground" which actually fit the lyrics of the song "Larry O'Gaff" as given in broadsides (as at the Bodley or American Memory). In particular, the original tune must have included a couple extra notes at the end of most lines, and a third section for the chorus.
