Some interviewees I remember as 'troupers'.

At the very top of that tree were the Collins sisters. Joan is now 92.

I remember a televised conversation I had with Joan. Her assistant decreed that the lighting must be subtle but Joan herself insisted on full on straight in the face spots. I had theories why this might be her preference.

Over the years I interviewed Joan and her sister Jackie a few times. It was always 'an event'.

The Collins sisters spoke to me in London at the end of the last century. Jackie was promoting her novel 'Thrill' about the glamorous world of Hollywood, and Joan was encouraging interest in her autobiography 'Second Act'. Both sisters were happy to talk about themselves.

Sadly Jackie died in 2015 .... but Joan marches on!
