He was a lovely, likeable man. One of the things that made him the king of chat show hosts was he made his guests the stars. He took a genuine interest in them, asked questions that would get the best out of them and his guests were not used as a platform for his own humour.
I owned his autobiography but never managed to finish it. Might still be at my parents.
Like MK, his early career was in journalism which really helped him with his questioning skills.
The interview with MK was great. I suspect that he wasn’t a natural DS fan as he was an enormous jazz connoisseur but he clearly took an interest in Mark.
Occasionally he did a whole episode just with one guest and, as already mentioned, the episode with McCartney is excellent and features Dave Gilmour playing guitar in his band.
