Patrick Troughton interviewed on Pebble Mill at One by the lovely Marian Foster, transmitted 21st December 1973. I think it's fair to assume that hospitality were a tad more generous than usual with the Blue Nun. Judging by the standard of camerawork I think the crew probably indulged too. The cameras here would be EMI 2001s.

Sadly, Patrick is no longer with us. A few years on - Marian is still just as lovely!
