"if you are un comfortable with doing this all you have to do is mention your amendments when you introduce the song"

I'm not uncomfortable about it - it's "what I do", after all! I just think it's a different process from what used to happen. But really we're only disagreeing about the terminology. As to making clear the scope of my amendments, I was already thinking of posting all the lyrics from my forthcoming Child Ballads CD on the web, accompanied by detials of the sources and some indication of where I've altered things. Just in case anyone was interested.
