1 April 2012 Last updated at 11:07 BST

Nicholas Parsons has not missed a single show of Radio 4's Just a Minute in 45 years and talked about the new TV version of the panel show - the second attempt to transfer the programme into vision.

The programme host recalled having to control Kenneth Williams, and how Clement Freud was not happy when the radio format was changed.

And he was asked about rumours connecting his father to Lady Thatcher.
