@@sarac.3259 she was on more things than open all hours, plus it’s just called respect and not being a constant nonce… which of course he knew nothing about.
I was thinking the same, though not because of Wogan, even if one or two of his questions were a bit odd, and certainly not because of the lovely Lynda Baron. But because of the audience reaction, or more accurately the eerily distinct lack thereof. Lynda, as an actress, would have been perfectly happy to chat away, smile and look like she was having a good time there, regardless of how it was going down with the audience, but Terry tended to rely on audience reaction to judge how to be, and here there are several times when he aims for a joke, or tries to change tack or gear in an attempt to give the audience something he thinks they want, and nothing gets any kind of reaction at all from the audience, so he is left almost floundering and trying to figure out for himself how it is going and which ways to steer the interview. When he suddenly mentions, apropos of nothing, the heating, and elicits a loud yes from the audience, he is blatantly slipping that in as a moderately subtle way of checking the audience can hear them and aren't actually asleep or something.
