I have that recording. His singing appeared so effortless and he could move from the most delicate passages to the most powerful with perfect control and transition. I don't really enjoy the tenor voice but his is exceptional. I cannot say "was exceptional" as his legacy will be with us for many decades to come; his magical voice will be almost immortal.
I understand his father was a singer too, and that he and Luciano attended as members of a choir, a music festival in Wales when Luciano was a youth. They won the competition and it was that successs which caused him to decide on a musical career.
What a gifted man.
Hearing him sing one time years ago (on TV, not live) ensured that I'd like opera. I was amazed at how meaningful he made music sound. The look on his face as he sang was one image that will endure too.
He will be missed I'm sure.
RIP big fella. Thought he was much younger than 71.
