Here's a
link to an essay Katy Evans-Bush published on Donaghy in
Contemporary Poetry Review after his death. It's a very good essay, and brings across both his personality and his poetry in a very winning way, I think. I only met him once, at my first West Chester conference in June 2004, but found him very engaging. He actually took the trouble to introduce me personally to Anthony Hecht, as I told him that I was a great admirer of his poetry. Both poets, as Tim has recorded, died that same year.
I greatly look forward to reading Dave's essay.
Adam, if you enjoyed Michael Donaghy's essay on prosody, you should get hold of his collected prose. It's a wonderful volume and I'm sure you'd find a lot to admire.
