From the Lord Warden section on Dover Ferry Photos:
September 26th 1954: A rough voyage from Boulogne to Dover was televised, the first time that a television programme was relayed direct from a ship at sea. During the course of the journey the late Richard Dimbleby, commenting on the bridge, was nearly drowned by a huge wave bursting over him.

Think I have posted these before. My brother-in-law rescued a bench from the Lord Warden when she finished, together with the nameplates from the lifeboats, and has it in his back garden in Dover. Also another one from the Normannia. Plus he has half the Canberra in his garage.
