There are legal and personal issues with these unpublished songs.
If you don't want to pay a single cent, or to be associated again with someone you don't like, then why put yourself in a frustrating situation by digging into your past?
In fact the mind will help you to forget that you even have unpublished songs. I'm talking about Brian, of course.
Ego beats any other card, as it was always the case with Queen.
