'I guess we will just have to agree to disagree, as to whether we prefer, "overseas in india", "or behind a trench in Flanders".'

I don't know where you get the idea I prefer that version. I don't. It doesn't make sense to me, and the original words do. It's a natural sort of thing to happen to the words, though, that a person should memorize them and they should morph into something that person's more familiar with.

I don't like changes made so someone can put their own 'stamp' on a song. I'm guessing Charlie removed the wounded whale in favor of the sun sinking to China because sunsets are prettier than wounded whales. But since you've changed words as well, I think what you really dislike are awkward changes for reasons you don't understand, and I completely agree with that.
