In the PBS show about the hymn Amazing Grace, Judy Collins says she was the first one to record it with all the “swoops” - I think that was the word she used. Her rendition seems like such a natural use of ornamentation that enhanced and then eventually replaced the original melodic line. Most renditions I hear now are like hers.
Anyway, as I said, her use of ornamentation is so natural on this already popular hymn, can it be there was no one before her who sang it with such “swoops”?
