UPDATE (7:50pm): In an e-mail, O’Donnell told me that he’s thrilled about this development:
I’m quite relieved and happy. This was the way it was supposed to have been heard 5 years ago.
My wife and I spent the afternoon with my now 93 year old father and we showed him that people were finally able to hear this work. It made our Christmas even better. My mother, his wife of over 60 years died a couple years ago and although she loved listening and shared it with some of her friends (she was a musician) she never understood why it wasn’t released.
I don’t know who actually did it but they have my blessing. I honestly don’t know how anyone could begrudge this any longer.
