Gerard, you say: I did some research on "The Dream Of Olwyn". If you had bothered to read my post of 03 Oct 02 - 08:34 PM, you would know that there are two different names,

1) Dreams Of Alwyn (the name that some give to the tune to your father's song)

and

2) The Dream of Olwen by Charles Williams. I give the information you have just researched, and far more, including links to midis of each tune, above.

(Malcolm, unlike some, I did pay attention to what was written, in this case by Barry Taylor. I was interested to know how such a thing came about, as Barry merely described what had happened. Can't say I have any further interest in this subject now.)
