She can, and she does, go on, and to hear her in full flow on her pet subject is impressive. As viewers of Shrink Rap will see, Stephenson has an endearing bedside manner, empathic and gentle, but subtly strong. In the show, this prompts remarkable results, whether it is Robin Williams talking about his fascination with weapons, David Blunkett struggling with his own emotional inarticulacy, or Sarah Ferguson, Duchess of York, revealing that Princess Diana once told her she was lucky to be at the bottom of the heap, because she (Diana) was on a pedestal, and had no way to go except down. Stephenson - who famously gatecrashed Prince Andrew's stag night with Diana and Sarah, all three dressed as policewomen - thinks that both princesses endured a lot of pain.
