Most of the information on the other thread IS pertinent and it's all there ALREADY. Can you correct that reference to Helen Creighton in the DT and the missing "í" in Buachaillín, as well as changing the tune?(Felipa 'FNS' is me) In my original message here I tried to do a concise, organised summary of the relevant thread, but you want it all copied here! I'm finding all this extra work frustrating.
Yes, Humours of Whiskey is usually sung to "Larry O'Gaff", but DT has it set to "Father O'Flynn" -- delete this comment about another song once you've fixed it!
