I wish I'd watched it now, but I've never liked Parkinson.
I always thought he was (is) a cranky, miserable, mumbling bore who always used to try to get a bit of a 'thing' going between him and any women guests that he fancied, who were on the show - sickening.
If he wasn't talking about/to Frank Sinatra, Billy Connolly or Sean Connery, it was some tosh about Yorkshire and his poor beginnings.
And I find it so naff for a former interviewer to now turn up on shows as the interviewee.
