If there was a room of 150 people that wanted to meet him, or 1,000 people, he stayed until the last person, and it wasn't a just move along sort of thing – he would take the time – he would remember everybody, he wanted to know about you, he wanted to know how you were doing."However, while the cause of Pierre Robert's death is still unclear, his radio colleague Preston Elliott said:"There was not an illness, we don't know why.
