I'm afraid it's one of those things that rather sets me off. I too wish that a lot more hard-to-find material was available via the web, and I find it frustrating that I haven't the time to do more in that direction myself. A lot of people seem to take it all for granted, not understanding the work involved (I've known folk complain bitterly that, for example, the whole of Bronson isn't out there for their use!) I'm glad that you're not one of those.

One thing I have managed to do is compile a listing of books and related materials that are available. By definition it won't (I hope) ever be complete, but you'll find the pages at http://www.folk-network.com/directory/links.html. They might save you some time at some point. Do please let me know about broken links or useful things omitted.

Returning to Tigery Orum, it seems that Irish Country Songs 4 is only available secondhand or as a print-on-demand job from Boosey & Hawkes, who presumably still hold copyright. I should think it's near its expiry date, though. It's on my list of things to pick up when the opportunity arises, but it's rather a long list.

The first line as quoted in the Roud Index is "There was a wise old woman and her story I will tell", so Lloyd obviously didn't take the song directly from Hughes; on at least one other occasion, though (Reynardine) he does seem to have used material from Hughes and other sources, and put it about that the resulting collation had been found in tradition, by him, in England. Although it may have been, Stephen Winick argues convincingly that it wasn't (see A. L. Lloyd and Reynardine: authenticity and authorship in the afterlife of a British broadside ballad -beware the annoying advert) and this might be another case; then again, it mightn't.

Always that problem when A L Lloyd enters the picture. A great man, but inclined to naughtiness.
