I don't have an answer to your question unfortunately, but I've noticed that Morrissey rarely ever mentions singers who are, let's say, "on par" with him in terms of lyrical skill or fanbase size/devotion. He has no problem going on about smaller acts like The Smoking Popes, Damien Dempsey, Kristeen Young and of course his boyhood heroes. But other than some offhanded negative remarks he never seems to weigh in on the likes of Pulp/Jarvis Cocker, Nick Cave, Elvis Costello (who's only about 5 years older than Moz), Paul Weller (despite Jam cover). Perhaps Jeff Buckley falls into that category.
