Hi Clanad........You are right to put forward the name of Jussi Bjorling. I'd include him in a top twenty or even ten list. He had a tremendous voice and could send a shiver down my spine; when perhaps I wanted a feeling of warmth with tears in my eyes. I hope you Know what I mean.
I agree that Pavarotti, the younger version, is a strong contender for a top spot and in a simillar position I would include Beniamino Gigli; who, regretably, kept on singing like a Boxer past his prime. (as do so many singers.)
Incidentally, I re-reposted my question in the history section of AB. So if you are interested in the response and my further ccomments; please click the following:-
