When I watched this approximately 3o minute segment - attached below - I was displeased that the video ran with some hesitations, but I waited them out and they rectified themselves, and it was worth it. I so much admired Welshman Richard Burton, yet was never fond of Cavett, seeing him as an overly self-effacing interviewer with a too cute smile. But Cavett is tolerable in this, and catching more of Burton's gifted stagecraft, and his heartfelt advice to fellow recovering drinkers ( we have many friends and family members thus afflicted) makes this a more than worthy SRN inclusion.
