Leadfingers, I hope you don't mean we will have to register a set list with some jobsworth at the local town hall in triplicate, at least 25 working days before a gig, accompanied by the appropriate licence and administration fee?

Or did you mean we should just announce who wrote the songs (if known of course)? I do that anyway as a matter of course, because I like to spread the word about artists I admire and whose songs I pinch to sing myself.
