My condolences to the family.
I was only an "Extra" in the film "Curtain Call", but Mr. Yates was truly a gentleman. I noticed that he treated everyone on staff with the upmost respect and his working ethics were at the highest level, he made us all feel that we were part of his family.
It was an honor to meet Peter and even more, working with him.
Rest in Peace my friend.
