Thanks for the tick of approval! FYI the bulk of my additions originate from an article originally on www.tradsongs.com, which seems to have disappeared but an archived copy is available here:

I could probably be accused of a degree of plagiarism but I could not find a lot elsewhere since the Folk Music Journal article is not accessible to me.

I note the WP entries for the songs "Leaving of Liverpool", "South Australia" and "Poor Paddy Works on the Railway" already have links to the WMD article (weapons of mass destruction??) - not sure what others should have at this time.

By the way if you can handle HTML, wikipedia syntax is pretty easy to learn especially if you look at what is behind other pages in "edit" mode. Basically it's just a mindset that once you are in seems (fairly) natural...

Best regards - Tony
