Every comedy journalist will have their own memories of Joan Rivers. Here are a couple of mine.  I had an insight into her real personality behind the bulletproof onstage confidence when I watched the acclaimed 2010 documentary about her life, A Piece Of Work. Part of the fly-on-the-wall doc followed her as she performed her one-woman play in London at the Leicester Square Theatre, A Work in Progress By a Life in Progress. After the press performance she was filmed reading her reviews in the back of a car.
