When I was in my early teens about 1960 or 1961, the interim pastor at our church, Temple Baptist of Hattiesburg, Mississippi, would bring Norman Treigle to sing religious music for us periodically. Norman Treigle's voice filled the whole, big, new auditorium - people's jaws dropped. It was announced ahead of time when he would be singing, so it got to the point that it was SRO when he sang - normally the auditorium was only about 1/3-1/2 filled. The calls for him to sing 'Ole Man River' got so strong that he eventually sang it in church - how I wish I had recorded it! I can remember remarking how amazing it was that his voice could fill the entire sanctuary without 'even a microphone'! :)
The fact that I still remember his stunning voice after all these years shows what an impression he made on me and everybody else, but I figured, well, he's an opera singer, so maybe they all sing like that - I had never heard an operatic voice in person. After reading this book, I realize that his voice was an unique as I thought back then!
An interesting side note - my grandmother was the church pianist/organist. She was amazingly talented, something of a local, small town star. Mr. Treigle was so impressed with her ability to transpose a song from one key to another on the spot that he asked her to travel with him on the road as his personal accompanist. My grandmother declined, because she didn't want to leave Hattiesburg, which he could understand, not liking travel himself, but it was always her biggest 'claim to fame' that Norman Treigle asked her to be his accompanist! He may not have been serious, but my grandmother thought he was!
I'm sorry this book didn't have any more information about the details of his singing and life in general, but I'm glad there's at least this one book. I'm going to be buying some of the few CDs available with his voice on it - he was a treasure!
