In re the original topic, I always want to know how the song came to be, and it sometimes influences my singing of it. I do still sing Amazing Grace, though not as something I believe, but rather as a song that has a good tune that lots of people know. The difference is, I don't lead it/start it.
At that same sing I sang "How Can I Keep From Singing?", a song that is closer to what I feel/believe.
Here's another dilemma I've run into: I liked "Song For Vic" [Borneo] a lot better before I learned why it was written. I still like it, but not as much. Borneo

And what about "It's All Part of Being a Pirate"? The rewrite by Tom Lewis is much better known, and funnier IMHO, but the original author doesn't want people doing Tom's version, just his. What's right practice there? Being a Pirate

And here's another dilemma: Mary Garvey rewrote "Deep Blue Sea" to make an excellent song about child slavery, based on a news story that later turned out to be inaccurate. Should we sing it anyway? child slavery

What do I do? I sing the songs I love in the versions I love, regardless of the PCness of it all.
Blessings,
Barbara
