When I posted the lyrics to "The Fairy's Love Song", I gave the name of the lady I learned it from, in that I think it was her own translation, and I think her effort deserves appreciation.
I write parodies. Someone takes credit for one of my best known. I've never made, and never expect to make a dime from that parody. But, dammit! I wrote it, I want the credit/blame for it. I think most writers feel the same way.
