The thread in which several people tried to translate & explain the term "deoch-an-doris" was this one:

Deoch an Dorus / Deoch-an-Doruis

Back in October and November of this year, I posted lyrics to all the Harry Lauder songs I could find. Most of them are in this thread: Lyr Add: Music-hall songs sung by Harry Lauder, but when there was already a thread about one of the songs, I updated the existing thread as necessary, and posted a link to it in my new thread.

When I came to A WEE DEOCH-AN-DORIS, I posted lyrics copied from the sheet music here. The messages following that one have some comments on the differences between the sheet music and the recording.
