I can't find the words thief/thieves/theft, or stole/stolen anywhere in the "Kathleen" thread.

Do you have an example of a "song origin" thread which "ends up with" a "list" of songs "The Irish" "stole" ? That is, it must be a thread about the origins of a song, there must be a list of songs (i.e. more than one) near the end of the thread, and in the same post with the list there must occur the words "The Irish stole" or similar words, with the object of "stole" being the songs on the list.
