Is the book "The wind that shakes the Barley" the one edited by Gareth James and published by the Belfast company Appletree Press?

If so, send me an e-mail (john@ulstersongs.com) and I'll see if I can get a second-hand copy - they occasionally turn up in bookshops in Northern Ireland.

The Wehman print (see above) of the "Three leaved shamrock" has the note "Copyright 1889, by Harding Brothers." It is possible that there will be versions in the American Sheet Music Collection at the Library of Congress.
