I had to laugh when I saw Cilla Black on Room 101 the other day and her offering was to put into the room, all the 'celebs' who say, "Don't you know who I am?"
But she was the worst of the lot for that kind of attitude!
I met her a couple of times back in the 60s and 70s, including having dinner with her and some of the other stars who were doing a summer season with her (I was a pop writer). Charming as long as everyone realised she was the centre of the world.
If the rules were not obeyed woe betide you!
