I can only explain my point of view. There are some reports or mention in different areas on the records pertaining to the subject. I do not believe it is all wishful thinking. I believe there may well be some things we just will not know for sure happened but, I can't rule things out either because I may not want to accept the real answer. At times, the company musician may have fired a gun. That is being an active participate in an event even if it's not 'official'.
