Yep, Got it OK from Milton Keynes via BBC iPlayer.
To save anyone from the effort, here's the direct link:

It's towards the end of the prog at about 20:28.
For those who haven't used BBC's iPlayer for a while, you now have to sign in to view stuff (& don't forget to log out too, otherwise they could track you LOL)....or send out a Transit Van with a spinning dustbin lid on the roof rack..
