Hi, Mcq,When I read the name of this thread, I thought someone had started a thread for the Kennedy's and "John-John's" disappearance. I feel sorry for a fmaily so full of promise and tragedy.
Anyway, I went looking for this poem on the net. Didn't find it, BUT I did find a great site of Irish poetry,with links to more poetry where you may be able to find it. BTW, the site I found also had a category of poems set to music. Here is the link: Irish Poetry w/bodhran sound clips!
or, type in: http://www.spinfo.uni-koeln.de/~dm/eire.html
good luck,
