The Princess and the Dark Horse

Via HERE:

The member of the Royal family most associated with the Beatles is Princess Margaret, who John Lennon referred to in one of his book as Priceless Margarine. On July 6, 1964 the Princess and Lord Snowdon attended the premier of 'A Hard Day's Night' at the London Pavilion. After the premier there was a private party at the Dorchester Hotel and the Princess and Lord Snowdon dropped by with some friends. The Princess and her entourage seemed to be enjoying themselves when George Harrison approached Walter Shenson, the film's producer and said, "When are we  going to eat?" Shenson told him that they couldn't possibly eat until Princess Margaret and Lord Snowdon had left. "Just be patient," he said. After another 15 minutes had elapsed, George walked up to the Princess and said, "Your Highness, we really are hungry and we can't eat until you two go."

"I see," said the Princess. "Well, in that case, we'd better run."

"That's great...now can you get the fuck outta here so we can have some Popeyes already?"
