I've comfortably approved of changes in the lyrics of two songs that I've written (although I thought that they both weakened the song. So be it. I've also had someone write another verse to one of my songs (thinking that it was a traditional song.) I told them that if they sang the song with their added verse, all I'd ask is to acknowledge that it wasn't part of the song as I wrote it.

That's not counting the people who've recorded songs of mine and changed the lyrics out of laziness.

Shakespeare I ain't.
