If it should prove true that Peter Kennedy did indeed "rip off" his source singers as has been alleged, what is the next step? IS there anything that can be done to rectify the alleged wrongdoing, given that Peter K (and I suspect many of his sources) are no longer around?

Or is it just a case of "setting the record straight" for historical reference purposes?

In other words, what is the purpose of digging this up after his death?
