Yes, dear Margaret had her faults, who does not ? But she did do some good. He was an importart patron of the dance arts especially, musical theatre as well. She was devoted in her duties to the Girl Guides [I think Princess Royal is doing that now, but not sure].
She was a snob but loved to pretend she was just "one of the party" And, she loved to PARTY indeed. She is still a fond legend from the 1960's here in SF. Because of her status, she was able to get herself and her friends out of trouble more than once.
Sadly, I never met her, though a very good friend did many times, interviewing her for some of his books. A couple of other friends partied with her a few times. However, I did see her a few times at engagements.
ALWAYS, drink in hand, Sometimes a cig as well.
She seemed to me, to be the only member, until Randy Andy, who knew how to have some fun and make the best of her privileges and restrictions.
I did indeed like the "old lush", a lot!
