Scoville, the term "hybrid" applies within species as well. Just ask Gregor Mendel.

(But those "human-animal hybrids" our dear President has expressed concern about, hey, we really do gotta watch out for them. ;-D

SharonA, Actually, I think Randy Beaver and Peter Horney are pretty well known around town and know each other well too.   (Just becareful about singing about them at church functions.)

Sharon, I was under the impression that Newton did not writer Amazing Grace until very late in his life, many years after his conversion.   Am I wrong?

I still think the whole sense of the lyrics to Amazing Grace is lost if it's not sung from the perspective of one who has felt the need for salvation from a "wretched" (unhappy, unfortunate, or miserable) condition by "Grace." If you're going to throw out "wretch," why not throw out "I once was lost ... was blind" too?    The whole idea of God loving and saving people by Grace flies against the interpretation of "wretch" as meaning "worthless."
I can understand why some people may not like the lyrics or the beliefs they express, but I'd rather people not sing it -- or just play the melody -- than try to turn it into a secular humanist song.
(As for the song being about Newton's own salvation and not about the ordeals of those he abused, I don't think any song needs to be all-encompassing in its theme.)

On Wagner's anti-Semitism, I can understand why Israel only recently has gotten beyond banning his music. But should Christians refrain from singing Fairest Lord Jesus because it was the hymn sung by the Crusaders as they slaughtered "infidels?"   After a few generations have passed by, I hope that artistic works can be appreciated on their own merits and not be censored because of the character flaws of those who created them.
