I glanced at some Dt threads and the idea seems to be to assemble different versions of one song in one place and to give references to published sources and sound recordings (bibliography and discography). I don't see them being used for correcting ERRORS in the DT.

I had been thinking of starting a DT study about Daniel O'Connell's Steam Engine / Making Babies By Steam but all the information is already in the thread - with very little chitchat.
The main problem is the search engine - although the song in the DT is entitled "Making Babies By Steam", I can't find it on the alphabetical DT list and nor by doing a search of "Making Babies" or "Babies By Steam". A search for "Daniel O'Connell gives me both threads and DT. But if I click at the DT version for forum discussions, I get one message for a thread about nonsense songs to dance tunes. No link to the two threads which contain lyrics, under the title "Daniel O'Connell's Steam Engine".
If the clickie at the DT page sent people to the relevant thread, they'd have plentty of background info.
I don't want to spend time copying sets of lyrics and having to add in the line breaks again. I just wanted the tune corrected and Joe Offer has now been duly alerted. There is a minor error in the transcription - "''An Buachaill_n Donn'" , "Buachaill_n" should read "Buachaillí". It's looking to me as if making corrections isn't the function of the DT study threads.
